Lets's calculate LCM of 30,16,32,714

2 30, 16, 32, 714
2 15, 8, 16, 357
2 15, 4, 8, 357
2 15, 2, 4, 357
3 15, 1, 2, 357
5, 1, 2, 119

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 5 x 1 x 2 x 119 = 57120

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/57120

Therefore, the GCF of Fractions 17/30,86/16,57/32,85/714 is 1/57120

Least Common Multiple of 30,16,32,714 with GCF Formula

Least Common Multiple of 30,16,32,714 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 30,16,32,714 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(30,16,32,714) = 2

common factors(in case of two or more numbers have common factors) = 96

GCF(30,16,32,714) x common factors =2 x 96 = 192

LCM(30,16,32,714) = ( 30 × 16 × 32 × 714 ) / 192

LCM(30,16,32,714) = 10967040 / 192

LCM(30,16,32,714) = 57120
