So the greatest common factor 73,45,79,31 is 1.

Lets's calculate LCM of 39,16,81,36

2 39, 16, 81, 36
2 39, 8, 81, 18
3 39, 4, 81, 9
3 13, 4, 27, 3
13, 4, 9, 1

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 13 x 4 x 9 x 1 = 16848

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/16848

Therefore, the GCF of Fractions 73/39,45/16,79/81,31/36 is 1/16848

Least Common Multiple of 39,16,81,36 with GCF Formula

Least Common Multiple of 39,16,81,36 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 39,16,81,36 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(39,16,81,36) = 1

common factors(in case of two or more numbers have common factors) = 108

GCF(39,16,81,36) x common factors =1 x 108 = 108

LCM(39,16,81,36) = ( 39 × 16 × 81 × 36 ) / 108

LCM(39,16,81,36) = 1819584 / 108

LCM(39,16,81,36) = 16848
