:1,3,241,723
Now, list down the factors of 665
:1,5,7,19,35,95,133,665
Greatest Common Factor
We found the factors 723,665 . The biggest common factor number is the GCF number.
So the greatest common factor 723,665 is 1.
Lets's calculate LCM of 491,500
Given numbers has no common factors except 1. So, there LCM is their product i.e 245500
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/245500
Therefore, the GCF of Fractions 723/491,665/500 is 1/245500
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 491,500 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(491,500) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(491,500) x common factors =1 x 1 = 1
LCM(491,500) = ( 491 × 500 ) / 1
LCM(491,500) = 245500 / 1
LCM(491,500) = 245500
