So the greatest common factor 84,80,12,86 is 2.

Lets's calculate LCM of 10,17,70,630

2 10, 17, 70, 630
5 5, 17, 35, 315
7 1, 17, 7, 63
1, 17, 1, 9

∴ So the LCM of the given numbers is 2 x 5 x 7 x 1 x 17 x 1 x 9 = 10710

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/10710

Therefore, the GCF of Fractions 84/10,80/17,12/70,86/630 is 2/10710

Least Common Multiple of 10,17,70,630 with GCF Formula

Least Common Multiple of 10,17,70,630 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 10,17,70,630 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(10,17,70,630) = 1

common factors(in case of two or more numbers have common factors) = 700

GCF(10,17,70,630) x common factors =1 x 700 = 700

LCM(10,17,70,630) = ( 10 × 17 × 70 × 630 ) / 700

LCM(10,17,70,630) = 7497000 / 700

LCM(10,17,70,630) = 10710
