Greatest Common Factor
We found the factors 90,258,489 . The biggest common factor number is the GCF number.
So the greatest common factor 90,258,489 is 3.
Lets's calculate LCM of 89,74,215
Given numbers has no common factors except 1. So, there LCM is their product i.e 1415990
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1415990
Therefore, the GCF of Fractions 90/89,258/74,489/215 is 3/1415990
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 89,74,215 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,74,215) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,74,215) x common factors =1 x 1 = 1
LCM(89,74,215) = ( 89 × 74 × 215 ) / 1
LCM(89,74,215) = 1415990 / 1
LCM(89,74,215) = 1415990
Here are some samples of GCF of Fractions calculations.
