Greatest Common Factor

We found the factors 74,90,20,65 . The biggest common factor number is the GCF number.
So the greatest common factor 74,90,20,65 is 1.

Lets's calculate LCM of 42,82,21,183

2 42, 82, 21, 183
3 21, 41, 21, 183
7 7, 41, 7, 61
1, 41, 1, 61

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 41 x 1 x 61 = 105042

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/105042

Least Common Multiple of 42,82,21,183 with GCF Formula

Least Common Multiple of 42,82,21,183 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 42,82,21,183 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,82,21,183) = 1

common factors(in case of two or more numbers have common factors) = 126

GCF(42,82,21,183) x common factors =1 x 126 = 126

LCM(42,82,21,183) = ( 42 × 82 × 21 × 183 ) / 126

LCM(42,82,21,183) = 13235292 / 126

LCM(42,82,21,183) = 105042
