So the greatest common factor 39,88,28,87 is 1.

Lets's calculate LCM of 34,69,69,54

2 34, 69, 69, 54
3 17, 69, 69, 27
23 17, 23, 23, 9
17, 1, 1, 9

∴ So the LCM of the given numbers is 2 x 3 x 23 x 17 x 1 x 1 x 9 = 21114

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21114

Therefore, the GCF of Fractions 39/34,88/69,28/69,87/54 is 1/21114

Least Common Multiple of 34,69,69,54 with GCF Formula

Least Common Multiple of 34,69,69,54 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 34,69,69,54 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(34,69,69,54) = 1

common factors(in case of two or more numbers have common factors) = 414

GCF(34,69,69,54) x common factors =1 x 414 = 414

LCM(34,69,69,54) = ( 34 × 69 × 69 × 54 ) / 414

LCM(34,69,69,54) = 8741196 / 414

LCM(34,69,69,54) = 21114
