The factors of 905 are 1, 5, 181, 905
The HCF of 665,905 is 5.
Lets's calculate GCF of 665,905
5 | 665, 905 |
133, 181 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 665
:1,5,7,19,35,95,133,665
Now, list down the factors of 905
:1,5,181,905
Greatest Common Factor
We found the factors 665,905 . The biggest common factor number is the GCF number.
So the greatest common factor 665,905 is 5.
Lets's calculate LCM of 320,377
Given numbers has no common factors except 1. So, there LCM is their product i.e 120640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/120640
Therefore, the GCF of Fractions 665/320,905/377 is 5/120640
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 320,377 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(320,377) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(320,377) x common factors =1 x 1 = 1
LCM(320,377) = ( 320 × 377 ) / 1
LCM(320,377) = 120640 / 1
LCM(320,377) = 120640
