Lets's calculate LCM of 70,72,252

2 70, 72, 252
2 35, 36, 126
3 35, 18, 63
3 35, 6, 21
7 35, 2, 7
5, 2, 1

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 7 x 5 x 2 x 1 = 2520

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2520

Therefore, the GCF of Fractions 43/70,98/72,340/252 is 1/2520

Least Common Multiple of 70,72,252 with GCF Formula

Least Common Multiple of 70,72,252 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 70,72,252 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,72,252) = 2

common factors(in case of two or more numbers have common factors) = 252

GCF(70,72,252) x common factors =2 x 252 = 504

LCM(70,72,252) = ( 70 × 72 × 252 ) / 504

LCM(70,72,252) = 1270080 / 504

LCM(70,72,252) = 2520
