So the greatest common factor 25,21,620 is 1.
Lets's calculate LCM of 868,212,433
2 | 868, 212, 433 |
2 | 434, 106, 433 |
217, 53, 433 |
∴ So the LCM of the given numbers is 2 x 2 x 217 x 53 x 433 = 19919732
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19919732
Therefore, the GCF of Fractions 25/868,21/212,620/433 is 1/19919732
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 868,212,433 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(868,212,433) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(868,212,433) x common factors =1 x 4 = 4
LCM(868,212,433) = ( 868 × 212 × 433 ) / 4
LCM(868,212,433) = 79678928 / 4
LCM(868,212,433) = 19919732
