So the greatest common factor 16,85,13,55 is 1.

Lets's calculate LCM of 55,99,70,64

2 55, 99, 70, 64
5 55, 99, 35, 32
11 11, 99, 7, 32
1, 9, 7, 32

∴ So the LCM of the given numbers is 2 x 5 x 11 x 1 x 9 x 7 x 32 = 221760

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/221760

Therefore, the GCF of Fractions 16/55,85/99,13/70,55/64 is 1/221760

Least Common Multiple of 55,99,70,64 with GCF Formula

Least Common Multiple of 55,99,70,64 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 55,99,70,64 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(55,99,70,64) = 1

common factors(in case of two or more numbers have common factors) = 110

GCF(55,99,70,64) x common factors =1 x 110 = 110

LCM(55,99,70,64) = ( 55 × 99 × 70 × 64 ) / 110

LCM(55,99,70,64) = 24393600 / 110

LCM(55,99,70,64) = 221760
