Greatest Common Factor
We found the factors 87,78,558 . The biggest common factor number is the GCF number.
So the greatest common factor 87,78,558 is 3.
Lets's calculate LCM of 551,857,132
Given numbers has no common factors except 1. So, there LCM is their product i.e 62331324
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/62331324
Therefore, the GCF of Fractions 87/551,78/857,558/132 is 3/62331324
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 551,857,132 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(551,857,132) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(551,857,132) x common factors =1 x 1 = 1
LCM(551,857,132) = ( 551 × 857 × 132 ) / 1
LCM(551,857,132) = 62331324 / 1
LCM(551,857,132) = 62331324
Here are some samples of GCF of Fractions calculations.
