So the greatest common factor 53,54,42,28 is 1.

Lets's calculate LCM of 23,12,97,705

3 23, 12, 97, 705
23, 4, 97, 235

∴ So the LCM of the given numbers is 3 x 23 x 4 x 97 x 235 = 6291420

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6291420

Therefore, the GCF of Fractions 53/23,54/12,42/97,28/705 is 1/6291420

Least Common Multiple of 23,12,97,705 with GCF Formula

Least Common Multiple of 23,12,97,705 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 23,12,97,705 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(23,12,97,705) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(23,12,97,705) x common factors =1 x 3 = 3

LCM(23,12,97,705) = ( 23 × 12 × 97 × 705 ) / 3

LCM(23,12,97,705) = 18874260 / 3

LCM(23,12,97,705) = 6291420
