Lets's calculate LCM of 72,98,63,286

2 72, 98, 63, 286
3 36, 49, 63, 143
3 12, 49, 21, 143
7 4, 49, 7, 143
4, 1, 7, 143

∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 4 x 1 x 7 x 143 = 504504

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/504504

Therefore, the GCF of Fractions 11/72,79/98,86/63,12/286 is 1/504504

Least Common Multiple of 72,98,63,286 with GCF Formula

Least Common Multiple of 72,98,63,286 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 72,98,63,286 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,98,63,286) = 1

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

GCF(72,98,63,286) x common factors =1 x 252 = 252

LCM(72,98,63,286) = ( 72 × 98 × 63 × 286 ) / 252

LCM(72,98,63,286) = 127135008 / 252

LCM(72,98,63,286) = 504504
