So the greatest common factor 644,405 is 1.

Lets's calculate LCM of 36,122

2 36, 122
18, 61

∴ So the LCM of the given numbers is 2 x 18 x 61 = 2196

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2196

Therefore, the GCF of Fractions 644/36,405/122 is 1/2196

Least Common Multiple of 36,122 with GCF Formula

Least Common Multiple of 36,122 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 36,122 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(36,122) = 2

common factors(in case of two or more numbers have common factors) = 1

GCF(36,122) x common factors =2 x 1 = 2

LCM(36,122) = ( 36 × 122 ) / 2

LCM(36,122) = 4392 / 2

LCM(36,122) = 2196
