So the greatest common factor 72,57,47,55 is 1.

Lets's calculate LCM of 58,90,75,772

2 58, 90, 75, 772
3 29, 45, 75, 386
5 29, 15, 25, 386
29, 3, 5, 386

∴ So the LCM of the given numbers is 2 x 3 x 5 x 29 x 3 x 5 x 386 = 5037300

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5037300

Therefore, the GCF of Fractions 72/58,57/90,47/75,55/772 is 1/5037300

Least Common Multiple of 58,90,75,772 with GCF Formula

Least Common Multiple of 58,90,75,772 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 58,90,75,772 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(58,90,75,772) = 1

common factors(in case of two or more numbers have common factors) = 60

GCF(58,90,75,772) x common factors =1 x 60 = 60

LCM(58,90,75,772) = ( 58 × 90 × 75 × 772 ) / 60

LCM(58,90,75,772) = 302238000 / 60

LCM(58,90,75,772) = 5037300
