So the greatest common factor 455,730 is 5.

Lets's calculate LCM of 21,1940

Given numbers has no common factors except 1. So, there LCM is their product i.e 40740

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/40740

Therefore, the GCF of Fractions 455/21,730/1940 is 5/40740

Least Common Multiple of 21,1940 with GCF Formula

Least Common Multiple of 21,1940 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 21,1940 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,1940) = 1

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

GCF(21,1940) x common factors =1 x 1 = 1

LCM(21,1940) = ( 21 × 1940 ) / 1

LCM(21,1940) = 40740 / 1

LCM(21,1940) = 40740
