The LCM of 30, 42, and 70 is 210
The Least Common Multiple (LCM) for 70 136 is 4,760.
2 x 2 x 7 = 28 2 x 3 x 7 = 42 2 x 2 x 3 x 7 = 84, the LCM
420 is the LCM of 70, 42 and 84
420
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
