Lets's calculate LCM of 85,78,68,17

2 85, 78, 68, 17
17 85, 39, 34, 17
5, 39, 2, 1

∴ So the LCM of the given numbers is 2 x 17 x 5 x 39 x 2 x 1 = 13260

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/13260

Therefore, the GCF of Fractions 84/85,30/78,44/68,933/17 is 1/13260

Least Common Multiple of 85,78,68,17 with GCF Formula

Least Common Multiple of 85,78,68,17 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 85,78,68,17 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(85,78,68,17) = 1

common factors(in case of two or more numbers have common factors) = 578

GCF(85,78,68,17) x common factors =1 x 578 = 578

LCM(85,78,68,17) = ( 85 × 78 × 68 × 17 ) / 578

LCM(85,78,68,17) = 7664280 / 578

LCM(85,78,68,17) = 13260
