So the greatest common factor 73,39,49,12 is 1.

Lets's calculate LCM of 56,38,72,57

2 56, 38, 72, 57
2 28, 19, 36, 57
2 14, 19, 18, 57
3 7, 19, 9, 57
19 7, 19, 3, 19
7, 1, 3, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 19 x 7 x 1 x 3 x 1 = 9576

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9576

Therefore, the GCF of Fractions 73/56,39/38,49/72,12/57 is 1/9576

Least Common Multiple of 56,38,72,57 with GCF Formula

Least Common Multiple of 56,38,72,57 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 56,38,72,57 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,38,72,57) = 1

common factors(in case of two or more numbers have common factors) = 912

GCF(56,38,72,57) x common factors =1 x 912 = 912

LCM(56,38,72,57) = ( 56 × 38 × 72 × 57 ) / 912

LCM(56,38,72,57) = 8733312 / 912

LCM(56,38,72,57) = 9576
