To find the highest common factor of 163,421, we have to find the factors of both numbers and list the highest common factor.
The factors of 163 are 1, 163
The factors of 421 are 1, 421
The HCF of 163,421 is 1.
Lets's calculate GCF of 163,421
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 163
:1,163
Now, list down the factors of 421
:1,421
Greatest Common Factor
We found the factors 163,421 . The biggest common factor number is the GCF number.
So the greatest common factor 163,421 is 1.
Lets's calculate LCM of 81,247
Given numbers has no common factors except 1. So, there LCM is their product i.e 20007
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20007
Therefore, the GCF of Fractions 163/81,421/247 is 1/20007
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 81,247 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,247) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,247) x common factors =1 x 1 = 1
LCM(81,247) = ( 81 × 247 ) / 1
LCM(81,247) = 20007 / 1
LCM(81,247) = 20007
