84 and 14, respectively.
LCM = product/HCF; HCF is 6 so LCM = 12 x 42 = 504
The least common multiple of 42 , 28 , 108 = 756
It is: 588
It is 252
HCF is 60 and the LCM is 360
6
hcf = 42, lcm = 84.
The LCM is: 126
LCM = product/HCF; HCF is 6 so LCM = 12 x 42 = 504
4 and 336, respectively.
LCM of 14 28 42 is 84.
The least common multiple of 14 and 21 is 42.14, 28, 42, 56 ...21, 42, 63, 84, ...
LCM(21, 28, 42) = 84
The LCM is: 84
The LCM is: 84
First you express the numbers as the product of their prime factors: 28 = 2x2x7 21 = 3x7 Next you find the HCF. In this case, the HCF is 7. Finally, you multiply the numbers together and divide by the HCF. 28x21/7 = 84 Therefore the LCM of 28 and 21 is 84.
The LCM is: 420
