1,3,9,17,51,153
Greatest Common Factor
We found the factors 157,209,153 . The biggest common factor number is the GCF number.
So the greatest common factor 157,209,153 is 1.
Lets's calculate LCM of 15,43,902
Given numbers has no common factors except 1. So, there LCM is their product i.e 581790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/581790
Therefore, the GCF of Fractions 157/15,209/43,153/902 is 1/581790
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 15,43,902 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,43,902) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(15,43,902) x common factors =1 x 1 = 1
LCM(15,43,902) = ( 15 × 43 × 902 ) / 1
LCM(15,43,902) = 581790 / 1
LCM(15,43,902) = 581790
Here are some samples of GCF of Fractions calculations.
