Since 30 is a factor of 90, the LCM is the larger of the two numbers, ie 90.
3 3*7=21 3*30=90 * * * * * That is the Greatest Common Factor, GCF, not the LCM. LCM(21, 90) = 630
90 and any factor of 90 for example, 10 and 90
There is a common factor of 2, so the answer is 2520.
The set of (90,90) has a GCF and an LCM of 90.The set of (-90,-90) has a GCF and an LCM of 90.
24.
LCM(2, 4, 6) = 12
The LCF is 1. The GCF is 45 The LCM is 90.
