Answer:
The LCM (Least Common Multiple) of 7 and 49 is 49.
Explanation:
To find the LCM (Least Common Multiple) of two numbers, one method is to list the multiples of each number and find the smallest multiple that both numbers share.
In this case, the LCM of 7 and 49 can be found by listing out the multiples of each number and finding the first multiple that both 7 and 49 have in common.
Multiples of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63, ...
Multiples of 49: 49, 98, 147, 196, 245, 294, ...
As we can see, the first multiple that both 7 and 49 share is 49, so 49 is the LCM of 7 and 49.
