How many Multiples of 7 are there between 100 and 1000?

To find out how many multiples of 7 there are between 100 and 1000, we can follow these steps:

• Step 1. Identifying the smallest multiple of 7 greater than or equal to 100: 100 ÷ 7 ≈ 15

Rounding upwards gives 15, so the smallest multiple of 7 is: 15 x 7 = 105

• Step 2. Identifying the largest multiple of 7 less than or equal to 1000: 1000 ÷ 7 ≈ 142

Rounding down gives 142, so the largest multiple of 7 is: 142 x 7 = 994

• Step 3. Counting numbers of the multiples of 7 from 105 to 994: 105, 112, 119, 126, 133, 140, …, 994

The common difference of this sequence of numbers is 7, the first term is 105 and the last is 994. The method for finding the number of terms: n = (994-105) ÷ 7 + 1 = 128

Thus, there are 128 multiples of 7 between 100 and 1000.

What are the Least Common Multiples of 7?

The least common multiples (LCM) of a single number, such as 7, is simply the number itself. Since 7 is a prime number, its LCM with any other number is simply the product of 7 and that number. Therefore the least common multiple of 7 with itself is 7, and for any other number n, the LCM of 7 and n is 7 x n.

If you are looking for the least common multiples of 7 with other numbers, here are a few examples:

• LCM(7, 1) = 7
• LCM(7, 2) = 14
• LCM(7, 3) = 21
• LCM(7, 4) = 28
• LCM(7, 5) = 35
• LCM(7, 6) = 42
• LCM(7, 8) = 56
• LCM(7, 9) = 63
• LCM(7, 10) = 70

And so on, with each LCM being a multiple of 7.

Solved Examples on Multiples of 7

Here are some examples of solved problems that provide answers to common questions about multiples of 7:

Q.1: What is the average of the first ten multiples of 7?

Answer: The average of the first ten multiples of 7 is equal to the sum of all multiples divided by 10.

Average = (7+14+21+28+35+42+49+56+63+70) ÷ 10

= 385 ÷ 10

= 38.5

Therefore, the required average is 38.5.

Q.2: Is 72 a multiple of 7 yes, or no?

Answer: No, 72 is not a 7 multiple. It is not multiple, as when divided by 7, it will leave a remainder of 2.

Q.3: What are the multiples of 7 that are less than 40?

Answer: The multiples of natural number 7, which are less than 40 are 7, 14, 21, 28, 35.

Q.4: What is the least common multiple of 6 and 7?

Answer: To find the least common multiple of 6 and 7, first we will write the multiples of each of the numbers.

• Multiples of 6 = 6, 12, 18, 24, 30, 36, 42, 48, 54, 60.
• Multiples of 7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70

Therefore, we can see, the LCM of 6 and 7 is 42.

FAQs on Multiples of 7

1.How to find multiples of a number?

To find the multiples of a number, you can simply multiply that number by different natural numbers. Here’s how you can do it:

• Start with the number itself. For example, if you are finding the multiples of 9, start with 9 x 1 = 9
• Multiply the number by successive natural numbers (1, 2, 3, 4, 5, etc. …) to get more multiples.

For example, to find the first few multiples of 9:

• 9 x 1 = 9
• 9 x 2 = 18
• 9 x 3 = 27
• 9 x 4 = 36
• 9 x 5 = 45

You can apply this same process to any number, and the multiples of a number are always evenly divisible by that number.

2.What is the lowest common multiple of 7?

The lowest common multiple (LCM) of 7 is simply 7 itself. This is because 7 is a prime number, and the smallest multiple of any prime number is the number itself.

• LCM(7, 7) = 7
• LCM (7, 1) = 7

In general, the LCM of any number with 7 (or any prime number) will be a multiple of 7, but the smallest LCM involving only 7 is always 7.

3.What are the first three common multiples of 7 and 11?

To find the first three common multiples of 7 and 11, we need to determine the least common multiples (LCM) of 7 and 11 and then list their multiples.

Since 7 and 11 are both prime numbers, their LCM is simply the product of the two numbers:

• LCM(7, 11) = 7 x 11 = 77

The first three common multiples of 7 and 11 are the first three multiples of 77 are:

• 77 x 1 = 77
• 77 x 2 = 154
• 77 x 3 = 231

So, the first three common multiples of 7 and 11 are: 77, 154, 231.
