Greatest Common Factor
We found the factors 84,56,492 . The biggest common factor number is the GCF number.
So the greatest common factor 84,56,492 is 4.
Lets's calculate LCM of 25,78,89
Given numbers has no common factors except 1. So, there LCM is their product i.e 173550
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/173550
Therefore, the GCF of Fractions 84/25,56/78,492/89 is 4/173550
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 25,78,89 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(25,78,89) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(25,78,89) x common factors =1 x 1 = 1
LCM(25,78,89) = ( 25 × 78 × 89 ) / 1
LCM(25,78,89) = 173550 / 1
LCM(25,78,89) = 173550
Here are some samples of GCF of Fractions calculations.
