Common multiples of 2, 5, and 7 are numbers that are divisible by all three of these numbers. To find the common multiples, you can start by listing the multiples of each number: 2 (2, 4, 6, 8, 10, ...), 5 (5, 10, 15, 20, ...), and 7 (7, 14, 21, 28, ...). The common multiples of 2, 5, and 7 are numbers that appear in all three lists, such as 70, 140, 210, and so on.
Well, isn't that just a happy little question! Common multiples are like friends that these numbers can all share. If we look at the multiples of 2, 5, and 7, we can find numbers like 70, 140, 210, and so on, where they all come together and have a good time. Just remember, there's no mistakes in math, just happy little numbers!
Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
60 and its multiples
lcm(2, 3, 5) = 30 → 2 digit common multiples are 30, 60, 90.

The common multiples of 2 and 5 are numbers that can be divided evenly by both 2 and 5. The common multiples of 2 and 5 are multiples of their least common multiple (LCM), which is 10. Therefore, the common multiples of 2 and 5 are all multiples of 10. Similarly, the common multiples of 2 and 6 are multiples of their LCM, which is 6. Therefore, the common multiples of 2 and 6 are all multiples of 6.
The Highest Common Factor is 1
