Lets's calculate LCM of 70,39,60,70

2 70, 39, 60, 70
3 35, 39, 30, 35
5 35, 13, 10, 35
7 7, 13, 2, 7
1, 13, 2, 1

∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 1 x 13 x 2 x 1 = 5460

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5460

Therefore, the GCF of Fractions 29/70,82/39,12/60,28/70 is 1/5460

Least Common Multiple of 70,39,60,70 with GCF Formula

Least Common Multiple of 70,39,60,70 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 70,39,60,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,39,60,70) = 1

common factors(in case of two or more numbers have common factors) = 2100

GCF(70,39,60,70) x common factors =1 x 2100 = 2100

LCM(70,39,60,70) = ( 70 × 39 × 60 × 70 ) / 2100

LCM(70,39,60,70) = 11466000 / 2100

LCM(70,39,60,70) = 5460
