So the greatest common factor 53,57,48,20 is 1.

Lets's calculate LCM of 14,55,48,720

2 14, 55, 48, 720
2 7, 55, 24, 360
2 7, 55, 12, 180
2 7, 55, 6, 90
3 7, 55, 3, 45
5 7, 55, 1, 15
7, 11, 1, 3

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 5 x 7 x 11 x 1 x 3 = 55440

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/55440

Therefore, the GCF of Fractions 53/14,57/55,48/48,20/720 is 1/55440

Least Common Multiple of 14,55,48,720 with GCF Formula

Least Common Multiple of 14,55,48,720 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 14,55,48,720 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(14,55,48,720) = 1

common factors(in case of two or more numbers have common factors) = 480

GCF(14,55,48,720) x common factors =1 x 480 = 480

LCM(14,55,48,720) = ( 14 × 55 × 48 × 720 ) / 480

LCM(14,55,48,720) = 26611200 / 480

LCM(14,55,48,720) = 55440
