So the greatest common factor 9,7,60,80 is 1.

Lets's calculate LCM of 39,20,76,889

2 39, 20, 76, 889
2 39, 10, 38, 889
39, 5, 19, 889

∴ So the LCM of the given numbers is 2 x 2 x 39 x 5 x 19 x 889 = 13174980

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/13174980

Therefore, the GCF of Fractions 9/39,7/20,60/76,80/889 is 1/13174980

Least Common Multiple of 39,20,76,889 with GCF Formula

Least Common Multiple of 39,20,76,889 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 39,20,76,889 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(39,20,76,889) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(39,20,76,889) x common factors =1 x 4 = 4

LCM(39,20,76,889) = ( 39 × 20 × 76 × 889 ) / 4

LCM(39,20,76,889) = 52699920 / 4

LCM(39,20,76,889) = 13174980
