1,5,23,25,115,575
Greatest Common Factor
We found the factors 800,575 . The biggest common factor number is the GCF number.
So the greatest common factor 800,575 is 25.
Lets's calculate LCM of 434,432
2 | 434, 432 |
217, 216 |
∴ So the LCM of the given numbers is 2 x 217 x 216 = 93744
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 25/93744
Therefore, the GCF of Fractions 800/434,575/432 is 25/93744
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 434,432 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(434,432) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(434,432) x common factors =2 x 1 = 2
LCM(434,432) = ( 434 × 432 ) / 2
LCM(434,432) = 187488 / 2
LCM(434,432) = 93744
