Greatest Common Factor
We found the factors 156,230,857 . The biggest common factor number is the GCF number.
So the greatest common factor 156,230,857 is 1.
Lets's calculate LCM of 129,690,877
3 | 129, 690, 877 |
43, 230, 877 |
∴ So the LCM of the given numbers is 3 x 43 x 230 x 877 = 26020590
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/26020590
Therefore, the GCF of Fractions 156/129,230/690,857/877 is 1/26020590
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 129,690,877 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(129,690,877) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(129,690,877) x common factors =1 x 3 = 3
LCM(129,690,877) = ( 129 × 690 × 877 ) / 3
LCM(129,690,877) = 78061770 / 3
LCM(129,690,877) = 26020590
