Lets's calculate LCM of 21,206

Given numbers has no common factors except 1. So, there LCM is their product i.e 4326

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/4326

Therefore, the GCF of Fractions 402/21,1377/206 is 3/4326

Least Common Multiple of 21,206 with GCF Formula

Least Common Multiple of 21,206 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 21,206 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,206) = 1

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

GCF(21,206) x common factors =1 x 1 = 1

LCM(21,206) = ( 21 × 206 ) / 1

LCM(21,206) = 4326 / 1

LCM(21,206) = 4326
