So the greatest common factor 17,47,92,157 is 1.

Lets's calculate LCM of 30,55,99,76

2 30, 55, 99, 76
3 15, 55, 99, 38
5 5, 55, 33, 38
11 1, 11, 33, 38
1, 1, 3, 38

∴ So the LCM of the given numbers is 2 x 3 x 5 x 11 x 1 x 1 x 3 x 38 = 37620

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/37620

Therefore, the GCF of Fractions 17/30,47/55,92/99,157/76 is 1/37620

Least Common Multiple of 30,55,99,76 with GCF Formula

Least Common Multiple of 30,55,99,76 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 30,55,99,76 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(30,55,99,76) = 1

common factors(in case of two or more numbers have common factors) = 330

GCF(30,55,99,76) x common factors =1 x 330 = 330

LCM(30,55,99,76) = ( 30 × 55 × 99 × 76 ) / 330

LCM(30,55,99,76) = 12414600 / 330

LCM(30,55,99,76) = 37620
