So the greatest common factor 3,7,21,57 is 1.


Lets's calculate LCM of 65,65,63,978

3 65, 65, 63, 978
5 65, 65, 21, 326
13 13, 13, 21, 326
1, 1, 21, 326

∴ So the LCM of the given numbers is 3 x 5 x 13 x 1 x 1 x 21 x 326 = 1334970

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1334970

Therefore, the GCF of Fractions 3/65,7/65,21/63,57/978 is 1/1334970

Least Common Multiple of 65,65,63,978 with GCF Formula

Least Common Multiple of 65,65,63,978 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 65,65,63,978 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(65,65,63,978) = 1

common factors(in case of two or more numbers have common factors) = 195

GCF(65,65,63,978) x common factors =1 x 195 = 195

LCM(65,65,63,978) = ( 65 × 65 × 63 × 978 ) / 195

LCM(65,65,63,978) = 260319150 / 195

LCM(65,65,63,978) = 1334970
