The factors of 489 are 1, 3, 163, 489
The HCF of 171,489 is 3.
Lets's calculate GCF of 171,489
3 | 171, 489 |
57, 163 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 171
:1,3,9,19,57,171
Now, list down the factors of 489
:1,3,163,489
Greatest Common Factor
We found the factors 171,489 . The biggest common factor number is the GCF number.
So the greatest common factor 171,489 is 3.
Lets's calculate LCM of 798,401
Given numbers has no common factors except 1. So, there LCM is their product i.e 319998
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/319998
Therefore, the GCF of Fractions 171/798,489/401 is 3/319998
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 798,401 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(798,401) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(798,401) x common factors =1 x 1 = 1
LCM(798,401) = ( 798 × 401 ) / 1
LCM(798,401) = 319998 / 1
LCM(798,401) = 319998
