This doesn't work. The LCM of a pair of numbers has to be equal to or larger than the largest number of the pair. If one of the numbers is 60, the other is 120. 60 and 120 have a GCF of 60, not an LCM.
The LCM of 60 and 18 is 180
The LCM of 30 and 60 is 60
30 and 60 have an LCM of 60.
5 and 60 have a gcf of 5 and a LCM of 60
15 and 20
1 and 5 have an LCM of 5.
The LCM is: 35
the lcm for 60 and 72 is 360.
The product of the GCF and LCM of a pair of numbers is equal to the product of the numbers.
Least Common Multiple (LCM) for 3 60 is 60.
The LCM is: 60
