Lets's calculate LCM of 65,68,17,432

2 65, 68, 17, 432
2 65, 34, 17, 216
17 65, 17, 17, 108
65, 1, 1, 108

∴ So the LCM of the given numbers is 2 x 2 x 17 x 65 x 1 x 1 x 108 = 477360

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/477360

Therefore, the GCF of Fractions 12/65,10/68,65/17,17/432 is 1/477360

Least Common Multiple of 65,68,17,432 with GCF Formula

Least Common Multiple of 65,68,17,432 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 65,68,17,432 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(65,68,17,432) = 1

common factors(in case of two or more numbers have common factors) = 68

GCF(65,68,17,432) x common factors =1 x 68 = 68

LCM(65,68,17,432) = ( 65 × 68 × 17 × 432 ) / 68

LCM(65,68,17,432) = 32460480 / 68

LCM(65,68,17,432) = 477360
