The factors of 905 are 1, 5, 181, 905
The HCF of 243,905 is 1.
Lets's calculate GCF of 243,905
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 243
:1,3,9,27,81,243
Now, list down the factors of 905
:1,5,181,905
Greatest Common Factor
We found the factors 243,905 . The biggest common factor number is the GCF number.
So the greatest common factor 243,905 is 1.
Lets's calculate LCM of 815,753
Given numbers has no common factors except 1. So, there LCM is their product i.e 613695
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/613695
Therefore, the GCF of Fractions 243/815,905/753 is 1/613695
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 815,753 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(815,753) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(815,753) x common factors =1 x 1 = 1
LCM(815,753) = ( 815 × 753 ) / 1
LCM(815,753) = 613695 / 1
LCM(815,753) = 613695
