Lets's calculate LCM of 54,32,18,72

2 54, 32, 18, 72
2 27, 16, 9, 36
2 27, 8, 9, 18
3 27, 4, 9, 9
3 3, 4, 3, 9
1, 4, 1, 3

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 1 x 4 x 1 x 3 = 864

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/864

Therefore, the GCF of Fractions 67/54,21/32,62/18,51/72 is 1/864

Least Common Multiple of 54,32,18,72 with GCF Formula

Least Common Multiple of 54,32,18,72 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 54,32,18,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(54,32,18,72) = 2

common factors(in case of two or more numbers have common factors) = 1296

GCF(54,32,18,72) x common factors =2 x 1296 = 2592

LCM(54,32,18,72) = ( 54 × 32 × 18 × 72 ) / 2592

LCM(54,32,18,72) = 2239488 / 2592

LCM(54,32,18,72) = 864
