One way to find he LCM of two or more numbers is to list the multiples of each until you reach one that the numbers have in common. For example:14, 28, 42, 56, 70, 84, 98, 112, 126, 140, 154, 168, 182, 196, 21035, 70, 105, 140, 175, 21042, 84, 126, 168, 210210 is the LCM of 14, 35, and 42.
420 is the LCM of 70, 42 and 84
420
The LCM is: 420
The Least Common Multiple (LCM) for 42 70 84 is 420.The Greatest Common Factor (GCF) for 42 70 84 is 14.
If that's really 4270 and 84, the GCF is 14 and the LCM is 25620. If that's 42, 70 and 84, the GCF is 14 and the LCM is 420.
The LCM is: 84
The LCM is 84.
hcf = 42, lcm = 84.
The LCM of 12 and 42 is 84.
The LCM would be 84, since 42 divides into 84 exactly twice !
LCM(21, 28, 42) = 84
