Lets's calculate LCM of 67,31,15,991

Given numbers has no common factors except 1. So, there LCM is their product i.e 30874605

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30874605

Therefore, the GCF of Fractions 48/67,21/31,50/15,18/991 is 1/30874605

Least Common Multiple of 67,31,15,991 with GCF Formula

Least Common Multiple of 67,31,15,991 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 67,31,15,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(67,31,15,991) = 1

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

GCF(67,31,15,991) x common factors =1 x 1 = 1

LCM(67,31,15,991) = ( 67 × 31 × 15 × 991 ) / 1

LCM(67,31,15,991) = 30874605 / 1

LCM(67,31,15,991) = 30874605
