So the greatest common factor 25,81,53 is 1.

Lets's calculate LCM of 20,130,516

2 20, 130, 516
2 10, 65, 258
5 5, 65, 129
1, 13, 129

∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 13 x 129 = 33540

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33540

Therefore, the GCF of Fractions 25/20,81/130,53/516 is 1/33540

Least Common Multiple of 20,130,516 with GCF Formula

Least Common Multiple of 20,130,516 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 20,130,516 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,130,516) = 2

common factors(in case of two or more numbers have common factors) = 20

GCF(20,130,516) x common factors =2 x 20 = 40

LCM(20,130,516) = ( 20 × 130 × 516 ) / 40

LCM(20,130,516) = 1341600 / 40

LCM(20,130,516) = 33540
