The factors of 111 are 1, 3, 37, 111
The HCF of 221,111 is 1.
Lets's calculate GCF of 221,111
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 221
:1,13,17,221
Now, list down the factors of 111
:1,3,37,111
Greatest Common Factor
We found the factors 221,111 . The biggest common factor number is the GCF number.
So the greatest common factor 221,111 is 1.
Lets's calculate LCM of 904,555
Given numbers has no common factors except 1. So, there LCM is their product i.e 501720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/501720
Therefore, the GCF of Fractions 221/904,111/555 is 1/501720
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 904,555 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(904,555) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(904,555) x common factors =1 x 1 = 1
LCM(904,555) = ( 904 × 555 ) / 1
LCM(904,555) = 501720 / 1
LCM(904,555) = 501720
