Lets's calculate LCM of 39,20,130,540

2 39, 20, 130, 540
2 39, 10, 65, 270
3 39, 5, 65, 135
5 13, 5, 65, 45
13 13, 1, 13, 9
1, 1, 1, 9

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 13 x 1 x 1 x 1 x 9 = 7020

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7020

Least Common Multiple of 39,20,130,540 with GCF Formula

Least Common Multiple of 39,20,130,540 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 39,20,130,540 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(39,20,130,540) = 1

common factors(in case of two or more numbers have common factors) = 7800

GCF(39,20,130,540) x common factors =1 x 7800 = 7800

LCM(39,20,130,540) = ( 39 × 20 × 130 × 540 ) / 7800

LCM(39,20,130,540) = 54756000 / 7800

LCM(39,20,130,540) = 7020
