Lets's calculate LCM of 42,24,817

2 42, 24, 817
3 21, 12, 817
7, 4, 817

∴ So the LCM of the given numbers is 2 x 3 x 7 x 4 x 817 = 137256

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/137256

Therefore, the GCF of Fractions 23/42,215/24,279/817 is 1/137256

Least Common Multiple of 42,24,817 with GCF Formula

Least Common Multiple of 42,24,817 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 42,24,817 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,24,817) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(42,24,817) x common factors =1 x 6 = 6

LCM(42,24,817) = ( 42 × 24 × 817 ) / 6

LCM(42,24,817) = 823536 / 6

LCM(42,24,817) = 137256
