So the greatest common factor 67,18,90,74 is 1.

Lets's calculate LCM of 17,40,30,116

2 17, 40, 30, 116
2 17, 20, 15, 58
5 17, 10, 15, 29
17, 2, 3, 29

∴ So the LCM of the given numbers is 2 x 2 x 5 x 17 x 2 x 3 x 29 = 59160

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/59160

Therefore, the GCF of Fractions 67/17,18/40,90/30,74/116 is 1/59160

Least Common Multiple of 17,40,30,116 with GCF Formula

Least Common Multiple of 17,40,30,116 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 17,40,30,116 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(17,40,30,116) = 1

common factors(in case of two or more numbers have common factors) = 40

GCF(17,40,30,116) x common factors =1 x 40 = 40

LCM(17,40,30,116) = ( 17 × 40 × 30 × 116 ) / 40

LCM(17,40,30,116) = 2366400 / 40

LCM(17,40,30,116) = 59160
