So the greatest common factor 19,77,42,99 is 1.

Lets's calculate LCM of 67,56,44,22

2 67, 56, 44, 22
2 67, 28, 22, 11
11 67, 14, 11, 11
67, 14, 1, 1

∴ So the LCM of the given numbers is 2 x 2 x 11 x 67 x 14 x 1 x 1 = 41272

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/41272

Therefore, the GCF of Fractions 19/67,77/56,42/44,99/22 is 1/41272

Least Common Multiple of 67,56,44,22 with GCF Formula

Least Common Multiple of 67,56,44,22 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 67,56,44,22 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(67,56,44,22) = 1

common factors(in case of two or more numbers have common factors) = 88

GCF(67,56,44,22) x common factors =1 x 88 = 88

LCM(67,56,44,22) = ( 67 × 56 × 44 × 22 ) / 88

LCM(67,56,44,22) = 3631936 / 88

LCM(67,56,44,22) = 41272
