Lets's calculate LCM of 91,56,90,176

2 91, 56, 90, 176
2 91, 28, 45, 88
2 91, 14, 45, 44
7 91, 7, 45, 22
13, 1, 45, 22

∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 13 x 1 x 45 x 22 = 720720

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/720720

Therefore, the GCF of Fractions 72/91,85/56,51/90,14/176 is 1/720720

Least Common Multiple of 91,56,90,176 with GCF Formula

Least Common Multiple of 91,56,90,176 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 91,56,90,176 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(91,56,90,176) = 1

common factors(in case of two or more numbers have common factors) = 112

GCF(91,56,90,176) x common factors =1 x 112 = 112

LCM(91,56,90,176) = ( 91 × 56 × 90 × 176 ) / 112

LCM(91,56,90,176) = 80720640 / 112

LCM(91,56,90,176) = 720720
