So the greatest common factor 171,257,990 is 1.

Lets's calculate LCM of 44,36,61

2 44, 36, 61
2 22, 18, 61
11, 9, 61

∴ So the LCM of the given numbers is 2 x 2 x 11 x 9 x 61 = 24156

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/24156

Therefore, the GCF of Fractions 171/44,257/36,990/61 is 1/24156

Least Common Multiple of 44,36,61 with GCF Formula

Least Common Multiple of 44,36,61 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 44,36,61 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(44,36,61) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(44,36,61) x common factors =1 x 4 = 4

LCM(44,36,61) = ( 44 × 36 × 61 ) / 4

LCM(44,36,61) = 96624 / 4

LCM(44,36,61) = 24156
