Lets's calculate LCM of 44,77,154

2 44, 77, 154
7 22, 77, 77
11 22, 11, 11
2, 1, 1

∴ So the LCM of the given numbers is 2 x 7 x 11 x 2 x 1 x 1 = 308

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/308

Therefore, the GCF of Fractions 30/44,92/77,172/154 is 2/308

Least Common Multiple of 44,77,154 with GCF Formula

Least Common Multiple of 44,77,154 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 44,77,154 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(44,77,154) = 11

common factors(in case of two or more numbers have common factors) = 154

GCF(44,77,154) x common factors =11 x 154 = 1694

LCM(44,77,154) = ( 44 × 77 × 154 ) / 1694

LCM(44,77,154) = 521752 / 1694

LCM(44,77,154) = 308
