Lets's calculate GCF of 721,902
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 721
:1,7,103,721
Now, list down the factors of 902
:1,2,11,22,41,82,451,902
Greatest Common Factor
We found the factors 721,902 . The biggest common factor number is the GCF number.
So the greatest common factor 721,902 is 1.
Lets's calculate LCM of 90,121
Given numbers has no common factors except 1. So, there LCM is their product i.e 10890
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10890
Therefore, the GCF of Fractions 721/90,902/121 is 1/10890
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 90,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,121) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(90,121) x common factors =1 x 1 = 1
LCM(90,121) = ( 90 × 121 ) / 1
LCM(90,121) = 10890 / 1
LCM(90,121) = 10890
