So the greatest common factor 10,12,63,17 is 1.

Lets's calculate LCM of 70,84,77,282

2 70, 84, 77, 282
3 35, 42, 77, 141
7 35, 14, 77, 47
5, 2, 11, 47

∴ So the LCM of the given numbers is 2 x 3 x 7 x 5 x 2 x 11 x 47 = 217140

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/217140

Therefore, the GCF of Fractions 10/70,12/84,63/77,17/282 is 1/217140

Least Common Multiple of 70,84,77,282 with GCF Formula

Least Common Multiple of 70,84,77,282 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 70,84,77,282 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,84,77,282) = 1

common factors(in case of two or more numbers have common factors) = 588

GCF(70,84,77,282) x common factors =1 x 588 = 588

LCM(70,84,77,282) = ( 70 × 84 × 77 × 282 ) / 588

LCM(70,84,77,282) = 127678320 / 588

LCM(70,84,77,282) = 217140
