Greatest Common Factor

We found the factors 48,45,97,42 . The biggest common factor number is the GCF number.
So the greatest common factor 48,45,97,42 is 1.

Lets's calculate LCM of 54,96,90,65

2 54, 96, 90, 65
3 27, 48, 45, 65
3 9, 16, 15, 65
5 3, 16, 5, 65
3, 16, 1, 13

∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 3 x 16 x 1 x 13 = 56160

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/56160

Therefore, the GCF of Fractions 48/54,45/96,97/90,42/65 is 1/56160

Least Common Multiple of 54,96,90,65 with GCF Formula

Least Common Multiple of 54,96,90,65 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 54,96,90,65 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(54,96,90,65) = 1

common factors(in case of two or more numbers have common factors) = 540

GCF(54,96,90,65) x common factors =1 x 540 = 540

LCM(54,96,90,65) = ( 54 × 96 × 90 × 65 ) / 540

LCM(54,96,90,65) = 30326400 / 540

LCM(54,96,90,65) = 56160
