Greatest Common Factor

We found the factors 74,70,15,250 . The biggest common factor number is the GCF number.
So the greatest common factor 74,70,15,250 is 1.

Lets's calculate LCM of 12,40,90,17

2 12, 40, 90, 17
2 6, 20, 45, 17
3 3, 10, 45, 17
5 1, 10, 15, 17
1, 2, 3, 17

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 1 x 2 x 3 x 17 = 6120

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6120

Therefore, the GCF of Fractions 74/12,70/40,15/90,250/17 is 1/6120

Least Common Multiple of 12,40,90,17 with GCF Formula

Least Common Multiple of 12,40,90,17 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 12,40,90,17 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,40,90,17) = 1

common factors(in case of two or more numbers have common factors) = 120

GCF(12,40,90,17) x common factors =1 x 120 = 120

LCM(12,40,90,17) = ( 12 × 40 × 90 × 17 ) / 120

LCM(12,40,90,17) = 734400 / 120

LCM(12,40,90,17) = 6120
