The LCM is 216
The number that both 7 and 8 can go into evenly is 56.
As 8 is even, and 3 is odd, I think only 1 can go into both.
104
It is: 200
16
The number is 120.
120
Their HCF is 8
The only number that goes into both 8 and 45 is 1
The smallest number that both 8 and 10 can go into is their least common multiple (LCM), which is the smallest multiple that both numbers share. The LCM of 8 and 10 is 40, as 8 x 5 = 40 and 10 x 4 = 40. Therefore, 40 is the number that both 8 and 10 can evenly divide into.
8
Either 1 or 40
