So the greatest common factor 561,3892 is 1.


Lets's calculate LCM of 20,220

2 20, 220
2 10, 110
5 5, 55
1, 11

∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 11 = 220

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/220

Therefore, the GCF of Fractions 561/20,3892/220 is 1/220

Least Common Multiple of 20,220 with GCF Formula

Least Common Multiple of 20,220 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 20,220 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,220) = 20

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

GCF(20,220) x common factors =20 x 1 = 20

LCM(20,220) = ( 20 × 220 ) / 20

LCM(20,220) = 4400 / 20

LCM(20,220) = 220
