Greatest Common Factor
We found the factors 789,491 . The biggest common factor number is the GCF number.
So the greatest common factor 789,491 is 1.
Lets's calculate LCM of 851,536
Given numbers has no common factors except 1. So, there LCM is their product i.e 456136
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/456136
Therefore, the GCF of Fractions 789/851,491/536 is 1/456136
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 851,536 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(851,536) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(851,536) x common factors =1 x 1 = 1
LCM(851,536) = ( 851 × 536 ) / 1
LCM(851,536) = 456136 / 1
LCM(851,536) = 456136
