1,199

Greatest Common Factor

We found the factors 420,199 . The biggest common factor number is the GCF number.
So the greatest common factor 420,199 is 1.

Lets's calculate LCM of 20,223

Given numbers has no common factors except 1. So, there LCM is their product i.e 4460

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4460

Therefore, the GCF of Fractions 420/20,199/223 is 1/4460

Least Common Multiple of 20,223 with GCF Formula

Least Common Multiple of 20,223 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 20,223 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,223) = 1

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

GCF(20,223) x common factors =1 x 1 = 1

LCM(20,223) = ( 20 × 223 ) / 1

LCM(20,223) = 4460 / 1

LCM(20,223) = 4460
