Lets's calculate LCM of 21,17,250

Given numbers has no common factors except 1. So, there LCM is their product i.e 89250

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/89250

Therefore, the GCF of Fractions 87/21,88/17,973/250 is 1/89250

Least Common Multiple of 21,17,250 with GCF Formula

Least Common Multiple of 21,17,250 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 21,17,250 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,17,250) = 1

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

GCF(21,17,250) x common factors =1 x 1 = 1

LCM(21,17,250) = ( 21 × 17 × 250 ) / 1

LCM(21,17,250) = 89250 / 1

LCM(21,17,250) = 89250
