So the greatest common factor 3,8,20,89 is 1.

Lets's calculate LCM of 78,87,52,756

2 78, 87, 52, 756
2 39, 87, 26, 378
3 39, 87, 13, 189
13 13, 29, 13, 63
1, 29, 1, 63

∴ So the LCM of the given numbers is 2 x 2 x 3 x 13 x 1 x 29 x 1 x 63 = 285012

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/285012

Therefore, the GCF of Fractions 3/78,8/87,20/52,89/756 is 1/285012

Least Common Multiple of 78,87,52,756 with GCF Formula

Least Common Multiple of 78,87,52,756 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 78,87,52,756 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,87,52,756) = 1

common factors(in case of two or more numbers have common factors) = 936

GCF(78,87,52,756) x common factors =1 x 936 = 936

LCM(78,87,52,756) = ( 78 × 87 × 52 × 756 ) / 936

LCM(78,87,52,756) = 266771232 / 936

LCM(78,87,52,756) = 285012
