So the greatest common factor 45,59,87,91 is 1.

Lets's calculate LCM of 58,55,11,45

5 58, 55, 11, 45
11 58, 11, 11, 9
58, 1, 1, 9

∴ So the LCM of the given numbers is 5 x 11 x 58 x 1 x 1 x 9 = 28710

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28710

Therefore, the GCF of Fractions 45/58,59/55,87/11,91/45 is 1/28710

Least Common Multiple of 58,55,11,45 with GCF Formula

Least Common Multiple of 58,55,11,45 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 58,55,11,45 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(58,55,11,45) = 1

common factors(in case of two or more numbers have common factors) = 55

GCF(58,55,11,45) x common factors =1 x 55 = 55

LCM(58,55,11,45) = ( 58 × 55 × 11 × 45 ) / 55

LCM(58,55,11,45) = 1579050 / 55

LCM(58,55,11,45) = 28710
