Greatest Common Factor

We found the factors 80,445 . The biggest common factor number is the GCF number.
So the greatest common factor 80,445 is 5.

Lets's calculate LCM of 101,121

Given numbers has no common factors except 1. So, there LCM is their product i.e 12221

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/12221

Therefore, the GCF of Fractions 80/101,445/121 is 5/12221

Least Common Multiple of 101,121 with GCF Formula

Least Common Multiple of 101,121 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 101,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(101,121) = 1

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

GCF(101,121) x common factors =1 x 1 = 1

LCM(101,121) = ( 101 × 121 ) / 1

LCM(101,121) = 12221 / 1

LCM(101,121) = 12221
