So the greatest common factor 68,30,18,827 is 1.

Lets's calculate LCM of 71,77,40,53

Given numbers has no common factors except 1. So, there LCM is their product i.e 11590040

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11590040

Therefore, the GCF of Fractions 68/71,30/77,18/40,827/53 is 1/11590040

Least Common Multiple of 71,77,40,53 with GCF Formula

Least Common Multiple of 71,77,40,53 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 71,77,40,53 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(71,77,40,53) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(71,77,40,53) x common factors =1 x 1 = 1

LCM(71,77,40,53) = ( 71 × 77 × 40 × 53 ) / 1

LCM(71,77,40,53) = 11590040 / 1

LCM(71,77,40,53) = 11590040
