Lets's calculate GCF of 231,273
3 | 231, 273 |
7 | 77, 91 |
11, 13 |
∴ So the GCF of the given numbers is 3 x 7 = 21
Now, list down the factors of 231
:1,3,7,11,21,33,77,231
Now, list down the factors of 273
:1,3,7,13,21,39,91,273
Greatest Common Factor
We found the factors 231,273 . The biggest common factor number is the GCF number.
So the greatest common factor 231,273 is 21.
Lets's calculate LCM of 449,579
Given numbers has no common factors except 1. So, there LCM is their product i.e 259971
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/259971
Therefore, the GCF of Fractions 231/449,273/579 is 21/259971
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 449,579 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(449,579) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(449,579) x common factors =1 x 1 = 1
LCM(449,579) = ( 449 × 579 ) / 1
LCM(449,579) = 259971 / 1
LCM(449,579) = 259971
