So the greatest common factor 18,84,99,74 is 1.

Lets's calculate LCM of 71,27,63,93

3 71, 27, 63, 93
3 71, 9, 21, 31
71, 3, 7, 31

∴ So the LCM of the given numbers is 3 x 3 x 71 x 3 x 7 x 31 = 415989

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/415989

Therefore, the GCF of Fractions 18/71,84/27,99/63,74/93 is 1/415989

Least Common Multiple of 71,27,63,93 with GCF Formula

Least Common Multiple of 71,27,63,93 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 71,27,63,93 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(71,27,63,93) = 1

common factors(in case of two or more numbers have common factors) = 27

GCF(71,27,63,93) x common factors =1 x 27 = 27

LCM(71,27,63,93) = ( 71 × 27 × 63 × 93 ) / 27

LCM(71,27,63,93) = 11231703 / 27

LCM(71,27,63,93) = 415989
