Lets's calculate LCM of 108,120,144

Least Common Multiple (LCM) of 108,120,144 By Common Division

2 108, 120, 144
2 54, 60, 72
2 27, 30, 36
3 27, 15, 18
3 9, 5, 6
3, 5, 2

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 3 x 5 x 2 = 2160

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/2160

Least Common Multiple of 108,120,144 with GCF Formula

Least Common Multiple of 108,120,144 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 108,120,144 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(108,120,144) = 12

common factors(in case of two or more numbers have common factors) = 72

GCF(108,120,144) x common factors =12 x 72 = 864

LCM(108,120,144) = ( 108 × 120 × 144 ) / 864

LCM(108,120,144) = 1866240 / 864

LCM(108,120,144) = 2160
