Lets's calculate LCM of 21,73,31,689

Given numbers has no common factors except 1. So, there LCM is their product i.e 32743347

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/32743347

Therefore, the GCF of Fractions 50/21,22/73,69/31,49/689 is 1/32743347

Least Common Multiple of 21,73,31,689 with GCF Formula

Least Common Multiple of 21,73,31,689 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 21,73,31,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,73,31,689) = 1

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

GCF(21,73,31,689) x common factors =1 x 1 = 1

LCM(21,73,31,689) = ( 21 × 73 × 31 × 689 ) / 1

LCM(21,73,31,689) = 32743347 / 1

LCM(21,73,31,689) = 32743347
