1,127
Greatest Common Factor
We found the factors 432,258,127 . The biggest common factor number is the GCF number.
So the greatest common factor 432,258,127 is 1.
Lets's calculate LCM of 642,241,915
3 | 642, 241, 915 |
214, 241, 305 |
∴ So the LCM of the given numbers is 3 x 214 x 241 x 305 = 47190210
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/47190210
Therefore, the GCF of Fractions 432/642,258/241,127/915 is 1/47190210
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 642,241,915 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(642,241,915) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(642,241,915) x common factors =1 x 3 = 3
LCM(642,241,915) = ( 642 × 241 × 915 ) / 3
LCM(642,241,915) = 141570630 / 3
LCM(642,241,915) = 47190210
