Greatest Common Factor
We found the factors 39,138,415 . The biggest common factor number is the GCF number.
So the greatest common factor 39,138,415 is 1.
Lets's calculate LCM of 647,675,722
Given numbers has no common factors except 1. So, there LCM is their product i.e 315315450
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/315315450
Therefore, the GCF of Fractions 39/647,138/675,415/722 is 1/315315450
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 647,675,722 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(647,675,722) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(647,675,722) x common factors =1 x 1 = 1
LCM(647,675,722) = ( 647 × 675 × 722 ) / 1
LCM(647,675,722) = 315315450 / 1
LCM(647,675,722) = 315315450
