Lets's calculate LCM of 38,57,506

2 38, 57, 506
19 19, 57, 253
1, 3, 253

∴ So the LCM of the given numbers is 2 x 19 x 1 x 3 x 253 = 28842

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28842

Therefore, the GCF of Fractions 13/38,40/57,490/506 is 1/28842

Least Common Multiple of 38,57,506 with GCF Formula

Least Common Multiple of 38,57,506 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 38,57,506 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(38,57,506) = 1

common factors(in case of two or more numbers have common factors) = 38

GCF(38,57,506) x common factors =1 x 38 = 38

LCM(38,57,506) = ( 38 × 57 × 506 ) / 38

LCM(38,57,506) = 1095996 / 38

LCM(38,57,506) = 28842
