Greatest Common Factor
We found the factors 289,638,653 . The biggest common factor number is the GCF number.
So the greatest common factor 289,638,653 is 1.
Lets's calculate LCM of 64,89,919
Given numbers has no common factors except 1. So, there LCM is their product i.e 5234624
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5234624
Therefore, the GCF of Fractions 289/64,638/89,653/919 is 1/5234624
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 64,89,919 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(64,89,919) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(64,89,919) x common factors =1 x 1 = 1
LCM(64,89,919) = ( 64 × 89 × 919 ) / 1
LCM(64,89,919) = 5234624 / 1
LCM(64,89,919) = 5234624
