Lets's calculate LCM of 70,78,25,884

2 70, 78, 25, 884
5 35, 39, 25, 442
13 7, 39, 5, 442
7, 3, 5, 34

∴ So the LCM of the given numbers is 2 x 5 x 13 x 7 x 3 x 5 x 34 = 464100

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/464100

Therefore, the GCF of Fractions 31/70,10/78,65/25,63/884 is 1/464100

Least Common Multiple of 70,78,25,884 with GCF Formula

Least Common Multiple of 70,78,25,884 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 70,78,25,884 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,78,25,884) = 1

common factors(in case of two or more numbers have common factors) = 260

GCF(70,78,25,884) x common factors =1 x 260 = 260

LCM(70,78,25,884) = ( 70 × 78 × 25 × 884 ) / 260

LCM(70,78,25,884) = 120666000 / 260

LCM(70,78,25,884) = 464100
