Greatest Common Factor

We found the factors 873,6887 . The biggest common factor number is the GCF number.
So the greatest common factor 873,6887 is 97.

Lets's calculate LCM of 21,220

Given numbers has no common factors except 1. So, there LCM is their product i.e 4620

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 97/4620

Therefore, the GCF of Fractions 873/21,6887/220 is 97/4620

Least Common Multiple of 21,220 with GCF Formula

Least Common Multiple of 21,220 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 21,220 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,220) = 1

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

GCF(21,220) x common factors =1 x 1 = 1

LCM(21,220) = ( 21 × 220 ) / 1

LCM(21,220) = 4620 / 1

LCM(21,220) = 4620
