Greatest Common Factor
We found the factors 74,46,156 . The biggest common factor number is the GCF number.
So the greatest common factor 74,46,156 is 2.
Lets's calculate LCM of 285,955,638
5 | 285, 955, 638 |
57, 191, 638 |
∴ So the LCM of the given numbers is 5 x 57 x 191 x 638 = 34729530
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/34729530
Therefore, the GCF of Fractions 74/285,46/955,156/638 is 2/34729530
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 285,955,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(285,955,638) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(285,955,638) x common factors =1 x 5 = 5
LCM(285,955,638) = ( 285 × 955 × 638 ) / 5
LCM(285,955,638) = 173647650 / 5
LCM(285,955,638) = 34729530
