Greatest Common Factor

We found the factors 3,9,72,15 . The biggest common factor number is the GCF number.
So the greatest common factor 3,9,72,15 is 3.

Lets's calculate LCM of 20,97,87,846

2 20, 97, 87, 846
3 10, 97, 87, 423
10, 97, 29, 141

∴ So the LCM of the given numbers is 2 x 3 x 10 x 97 x 29 x 141 = 23797980

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/23797980

Therefore, the GCF of Fractions 3/20,9/97,72/87,15/846 is 3/23797980

Least Common Multiple of 20,97,87,846 with GCF Formula

Least Common Multiple of 20,97,87,846 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 20,97,87,846 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,97,87,846) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(20,97,87,846) x common factors =1 x 6 = 6

LCM(20,97,87,846) = ( 20 × 97 × 87 × 846 ) / 6

LCM(20,97,87,846) = 142787880 / 6

LCM(20,97,87,846) = 23797980
