What are the common multiples of 2 and 5?

Answer 1

The common multiples of 2 and 5 are 10, 20, 30, 40, etc.

In detail:

A common multiple is a number divisible by both (or all) numbers: 2 and 5, here.

Knowing that all numbers divisible by 2 have a 0, 2, 4, 6, or 8 in the ones place combined with the knowledge that all numbers divisible by 5 end with 0 or 5 (excluding 0 in both cases), we can say the only multiples of each number that are common to both are numbers that end with 0.

Another way of analyzing this problem is to say that both 5 and 2 are factors. 10 is clearly a multiple of 5 and 2 because 2(5)=10. Any number divisible by 10 is thus also divisible by 2 and 5. All numbers divisible by 10 end in 0. Thus, a number ends in 0 if and only if it is divisible by 2 and 5.

Answer: Common multiples of 2 and 5 end with zero.

Answer 2

The common multiples of 2 and 5 are numbers that can be divided evenly by both 2 and 5. The multiples of 2 are 2, 4, 6, 8, 10, 12, and so on. The multiples of 5 are 5, 10, 15, 20, 25, and so on. The common multiples of 2 and 5 are numbers that appear in both lists, such as 10, 20, 30, and so forth.

Answer 3

Well, honey, the common multiples of 2 and 5 are numbers that both 2 and 5 can divide into evenly. So, we're looking at numbers that are multiples of both 2 and 5. The common multiples of 2 and 5 are 10, 20, 30, 40, and so on. Hope that clears things up for ya, sugar!

Answer 4

Ah, isn't that a happy little question! The common multiples of 2 and 5 are numbers that both 2 and 5 can evenly go into. So, if we list out the multiples of 2 (2, 4, 6, 8, 10, 12, ...) and the multiples of 5 (5, 10, 15, 20, ...), we can see that their common multiples are numbers like 10, 20, 30, and so on. Just like painting, finding common multiples is all about seeing patterns and working with what you have.
