Greatest Common Factor

We found the factors 16,84,33,690 . The biggest common factor number is the GCF number.
So the greatest common factor 16,84,33,690 is 1.

Lets's calculate LCM of 63,16,18,90

2 63, 16, 18, 90
3 63, 8, 9, 45
3 21, 8, 3, 15
7, 8, 1, 5

∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 8 x 1 x 5 = 5040

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5040

Least Common Multiple of 63,16,18,90 with GCF Formula

Least Common Multiple of 63,16,18,90 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 63,16,18,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(63,16,18,90) = 1

common factors(in case of two or more numbers have common factors) = 324

GCF(63,16,18,90) x common factors =1 x 324 = 324

LCM(63,16,18,90) = ( 63 × 16 × 18 × 90 ) / 324

LCM(63,16,18,90) = 1632960 / 324

LCM(63,16,18,90) = 5040
