Greatest Common Factor
We found the factors 655,589 . The biggest common factor number is the GCF number.
So the greatest common factor 655,589 is 1.
Lets's calculate LCM of 651,640
Given numbers has no common factors except 1. So, there LCM is their product i.e 416640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/416640
Therefore, the GCF of Fractions 655/651,589/640 is 1/416640
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 651,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(651,640) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(651,640) x common factors =1 x 1 = 1
LCM(651,640) = ( 651 × 640 ) / 1
LCM(651,640) = 416640 / 1
LCM(651,640) = 416640
