Lets's calculate LCM of 13,85,159

Given numbers has no common factors except 1. So, there LCM is their product i.e 175695

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/175695

Therefore, the GCF of Fractions 80/13,66/85,402/159 is 2/175695

Least Common Multiple of 13,85,159 with GCF Formula

Least Common Multiple of 13,85,159 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 13,85,159 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,85,159) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(13,85,159) x common factors =1 x 1 = 1

LCM(13,85,159) = ( 13 × 85 × 159 ) / 1

LCM(13,85,159) = 175695 / 1

LCM(13,85,159) = 175695
