The factors of 291 are 1, 3, 97, 291
The HCF of 249,291 is 3.
Lets's calculate GCF of 249,291
3 | 249, 291 |
83, 97 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 249
:1,3,83,249
Now, list down the factors of 291
:1,3,97,291
Greatest Common Factor
We found the factors 249,291 . The biggest common factor number is the GCF number.
So the greatest common factor 249,291 is 3.
Lets's calculate LCM of 331,385
Given numbers has no common factors except 1. So, there LCM is their product i.e 127435
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/127435
Therefore, the GCF of Fractions 249/331,291/385 is 3/127435
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 331,385 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(331,385) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(331,385) x common factors =1 x 1 = 1
LCM(331,385) = ( 331 × 385 ) / 1
LCM(331,385) = 127435 / 1
LCM(331,385) = 127435
