The greatest common multiple of 10 and 18 is infinite.However, I suspect you want either:the greatest common factor of 10 and 18 which is the largest number which divides both 10 and 18 and is 2; orthe lowest common multiple of 10 and 18 which is smallest number into which both 10 and 18 divide (ie the smallest number which is a multiple of both 10 and 18) and is 90

10
It is 90.
The least common factor - the smallest number which divides them all - is 1.
60
10. (10*1=10, 5*2=10)
Five is prime and a factor of both numbers.
1 and 5
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.
