:1,2,193,386
Now, list down the factors of 143
:1,11,13,143
Greatest Common Factor
We found the factors 386,143 . The biggest common factor number is the GCF number.
So the greatest common factor 386,143 is 1.
Lets's calculate LCM of 789,722
Given numbers has no common factors except 1. So, there LCM is their product i.e 569658
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/569658
Therefore, the GCF of Fractions 386/789,143/722 is 1/569658
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 789,722 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(789,722) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(789,722) x common factors =1 x 1 = 1
LCM(789,722) = ( 789 × 722 ) / 1
LCM(789,722) = 569658 / 1
LCM(789,722) = 569658
