So the greatest common factor 70,34,52,79 is 1.

Lets's calculate LCM of 80,70,51,63

2 80, 70, 51, 63
3 40, 35, 51, 63
5 40, 35, 17, 21
7 8, 7, 17, 21
8, 1, 17, 3

∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 8 x 1 x 17 x 3 = 85680

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/85680

Therefore, the GCF of Fractions 70/80,34/70,52/51,79/63 is 1/85680

Least Common Multiple of 80,70,51,63 with GCF Formula

Least Common Multiple of 80,70,51,63 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 80,70,51,63 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,70,51,63) = 1

common factors(in case of two or more numbers have common factors) = 210

GCF(80,70,51,63) x common factors =1 x 210 = 210

LCM(80,70,51,63) = ( 80 × 70 × 51 × 63 ) / 210

LCM(80,70,51,63) = 17992800 / 210

LCM(80,70,51,63) = 85680
