:1,11,73,803
Now, list down the factors of 641
:1,641
Greatest Common Factor
We found the factors 803,641 . The biggest common factor number is the GCF number.
So the greatest common factor 803,641 is 1.
Lets's calculate LCM of 676,243
Given numbers has no common factors except 1. So, there LCM is their product i.e 164268
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/164268
Therefore, the GCF of Fractions 803/676,641/243 is 1/164268
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 676,243 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(676,243) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(676,243) x common factors =1 x 1 = 1
LCM(676,243) = ( 676 × 243 ) / 1
LCM(676,243) = 164268 / 1
LCM(676,243) = 164268
