In mathematics, multiples are numbers that are obtained by multiplying a given number by any other whole number. For example, the multiples of 7 are obtained by multiplying 7 by any other whole number, such as 1, 2, 3, and so on.
In this article, we will explore the multiples of 7 and provide examples and tables to help you understand them better.
What are the multiples of 7?
The multiples of 7 are obtained by multiplying 7 by any other whole number. Some of the multiples of 7 are:
- 7 x 1 = 7
- 7 x 2 = 14
- 7 x 3 = 21
- 7 x 4 = 28
- 7 x 5 = 35
- 7 x 6 = 42
To find the multiples of 7, we simply multiply 7 by any whole number, starting from 1 and going up in increments of 1.
For example, to find the 7th multiple of 7, we can multiply 7 by 7, which gives us 49. To find the 10th multiple of 7, we can multiply 7 by 10, which gives us 70.

Additional Information
- The multiples of 7 are all odd or even numbers, depending on the number being multiplied by 7.
- The multiples of 7 can be used to determine divisibility by 7. If a number is divisible by 7, then it must be a multiple of 7.
- The sum of the digits of any multiple of 7 is also a multiple of 7. For example, the sum of the digits of 21 (2+1=3) is not a multiple of 7, but the sum of the digits of 28 (2+8=10) is a multiple of 7.
FAQs on multiples of 7
- What is the smallest multiple of 7? – The smallest multiple of 7 is 7.
- What is the largest multiple of 7? – There is no largest multiple of 7, as the multiples of 7 go on infinitely.
- Are all multiples of 7 odd or even numbers? – The multiples of 7 can be either odd or even numbers, depending on the number being multiplied by 7.
- What is the sum of the first 10 multiples of 7? – The sum of the first 10 multiples of 7 is 385.
- What is the sum of the digits of the 5th multiple of 7? – The sum of the digits of the 5th multiple of 7, which is 35, is 8 (3+5).
- Can multiples of 7 be used to determine divisibility by other numbers? – Yes, multiples of 7 can be used to determine divisibility by other numbers. For example, if a number is divisible by both 7 and 3, then it must be divisible by 21, which is the product of 7 and 3.
