Find the common factors and multiply those just once, then multiply all other factors.
4 = 1 x 2 x 2
14 = 1 x 2 x 7
8 = 1 x 2 x 2 x 2
26 = 1 x 2 x 13
I bolded the factors that need to be multiplied to get the LCF.
1 x 2 x 2 x 7 x 2 x 13 = 728
For 14, 8, 7, 4 the LCM is: 56
The LCM is 56.
The LCM is 168.
The LCM is 280.
True, but the LCM of 8, 14 and 18 is 504.
The LCM of 4, 8, and 14 is 56
LCM(4, 8, 14) = 56.
LCM(8, 4, 14) = 56.
56. (8 * 7 = 56) (14 * 4 = 56)
LCM(8, 14) = 56
The LCM is 168.
The LCM is 56.
