So the greatest common factor 639,282,640 is 1.

Lets's calculate LCM of 52,36,61

2 52, 36, 61
2 26, 18, 61
13, 9, 61

∴ So the LCM of the given numbers is 2 x 2 x 13 x 9 x 61 = 28548

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28548

Therefore, the GCF of Fractions 639/52,282/36,640/61 is 1/28548

Least Common Multiple of 52,36,61 with GCF Formula

Least Common Multiple of 52,36,61 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 52,36,61 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(52,36,61) = 1

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

GCF(52,36,61) x common factors =1 x 4 = 4

LCM(52,36,61) = ( 52 × 36 × 61 ) / 4

LCM(52,36,61) = 114192 / 4

LCM(52,36,61) = 28548
