Answer:
Some common multiples of 6 and 7 are 42, 84, 126, 252, 504.
Explanation:
A common multiple is a whole number that is a shared multiple of each set of numbers. The multiples that are common to two or more numbers are called the common multiples of those numbers.
For example:
Multiples of 6 are: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, …
Multiples of 7 are: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, ...
So we have to find numbers which are the same in each set sooo.... 42 is a common multiple.
If we keep on going we find numbers such as...
42, 84, 126, 252, 504
