Greatest Common Factor
We found the factors 91,910,143 . The biggest common factor number is the GCF number.
So the greatest common factor 91,910,143 is 13.
Lets's calculate LCM of 22,68,638
2 | 22, 68, 638 |
11 | 11, 34, 319 |
1, 34, 29 |
∴ So the LCM of the given numbers is 2 x 11 x 1 x 34 x 29 = 21692
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/21692
Therefore, the GCF of Fractions 91/22,910/68,143/638 is 13/21692
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 22,68,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(22,68,638) = 2
common factors(in case of two or more numbers have common factors) = 22
GCF(22,68,638) x common factors =2 x 22 = 44
LCM(22,68,638) = ( 22 × 68 × 638 ) / 44
LCM(22,68,638) = 954448 / 44
LCM(22,68,638) = 21692
