So the greatest common factor 63,90,150 is 3.


Lets's calculate LCM of 72,90,126

2 72, 90, 126
3 36, 45, 63
3 12, 15, 21
4, 5, 7

∴ So the LCM of the given numbers is 2 x 3 x 3 x 4 x 5 x 7 = 2520

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/2520

Therefore, the GCF of Fractions 63/72,90/90,150/126 is 3/2520

Least Common Multiple of 72,90,126 with GCF Formula

Least Common Multiple of 72,90,126 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 72,90,126 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,90,126) = 18

common factors(in case of two or more numbers have common factors) = 18

GCF(72,90,126) x common factors =18 x 18 = 324

LCM(72,90,126) = ( 72 × 90 × 126 ) / 324

LCM(72,90,126) = 816480 / 324

LCM(72,90,126) = 2520
