Lets's calculate LCM of 56,61,220

2 56, 61, 220
2 28, 61, 110
14, 61, 55

∴ So the LCM of the given numbers is 2 x 2 x 14 x 61 x 55 = 187880

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/187880

Therefore, the GCF of Fractions 45/56,401/61,717/220 is 1/187880

Least Common Multiple of 56,61,220 with GCF Formula

Least Common Multiple of 56,61,220 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 56,61,220 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,61,220) = 1

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

GCF(56,61,220) x common factors =1 x 4 = 4

LCM(56,61,220) = ( 56 × 61 × 220 ) / 4

LCM(56,61,220) = 751520 / 4

LCM(56,61,220) = 187880
