Lets's calculate LCM of 42,81,32,259

2 42, 81, 32, 259
3 21, 81, 16, 259
7 7, 27, 16, 259
1, 27, 16, 37

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 27 x 16 x 37 = 671328

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/671328

Therefore, the GCF of Fractions 39/42,82/81,44/32,19/259 is 1/671328

Least Common Multiple of 42,81,32,259 with GCF Formula

Least Common Multiple of 42,81,32,259 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 42,81,32,259 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,81,32,259) = 1

common factors(in case of two or more numbers have common factors) = 42

GCF(42,81,32,259) x common factors =1 x 42 = 42

LCM(42,81,32,259) = ( 42 × 81 × 32 × 259 ) / 42

LCM(42,81,32,259) = 28195776 / 42

LCM(42,81,32,259) = 671328
