Greatest Common Factor

We found the factors 22,81,39,66 . The biggest common factor number is the GCF number.
So the greatest common factor 22,81,39,66 is 1.

Lets's calculate LCM of 20,30,95,92

2 20, 30, 95, 92
2 10, 15, 95, 46
5 5, 15, 95, 23
1, 3, 19, 23

∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 3 x 19 x 23 = 26220

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/26220

Therefore, the GCF of Fractions 22/20,81/30,39/95,66/92 is 1/26220

Least Common Multiple of 20,30,95,92 with GCF Formula

Least Common Multiple of 20,30,95,92 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 20,30,95,92 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,30,95,92) = 1

common factors(in case of two or more numbers have common factors) = 200

GCF(20,30,95,92) x common factors =1 x 200 = 200

LCM(20,30,95,92) = ( 20 × 30 × 95 × 92 ) / 200

LCM(20,30,95,92) = 5244000 / 200

LCM(20,30,95,92) = 26220
