So the greatest common factor 27,43,19,65 is 1.

Lets's calculate LCM of 57,45,16,27

3 57, 45, 16, 27
3 19, 15, 16, 9
19, 5, 16, 3

∴ So the LCM of the given numbers is 3 x 3 x 19 x 5 x 16 x 3 = 41040

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/41040

Therefore, the GCF of Fractions 27/57,43/45,19/16,65/27 is 1/41040

Least Common Multiple of 57,45,16,27 with GCF Formula

Least Common Multiple of 57,45,16,27 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 57,45,16,27 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(57,45,16,27) = 1

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

GCF(57,45,16,27) x common factors =1 x 27 = 27

LCM(57,45,16,27) = ( 57 × 45 × 16 × 27 ) / 27

LCM(57,45,16,27) = 1108080 / 27

LCM(57,45,16,27) = 41040
