The HCF of 324,421 is 1.
Lets's calculate GCF of 324,421
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 324
:1,2,3,4,6,9,12,18,27,36,54,81,108,162,324
Now, list down the factors of 421
:1,421
Greatest Common Factor
We found the factors 324,421 . The biggest common factor number is the GCF number.
So the greatest common factor 324,421 is 1.
Lets's calculate LCM of 27,689
Given numbers has no common factors except 1. So, there LCM is their product i.e 18603
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18603
Therefore, the GCF of Fractions 324/27,421/689 is 1/18603
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 27,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(27,689) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(27,689) x common factors =1 x 1 = 1
LCM(27,689) = ( 27 × 689 ) / 1
LCM(27,689) = 18603 / 1
LCM(27,689) = 18603
