So the greatest common factor 725,251,390 is 1.
Lets's calculate LCM of 289,412,411
Given numbers has no common factors except 1. So, there LCM is their product i.e 48936948
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/48936948
Therefore, the GCF of Fractions 725/289,251/412,390/411 is 1/48936948
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 289,412,411 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(289,412,411) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(289,412,411) x common factors =1 x 1 = 1
LCM(289,412,411) = ( 289 × 412 × 411 ) / 1
LCM(289,412,411) = 48936948 / 1
LCM(289,412,411) = 48936948
Here are some samples of GCF of Fractions calculations.
