:1,2,3,6,9,18,27,54,81,162,243,486
Greatest Common Factor
We found the factors 405,486 . The biggest common factor number is the GCF number.
So the greatest common factor 405,486 is 81.
Lets's calculate LCM of 365,305
5 | 365, 305 |
73, 61 |
∴ So the LCM of the given numbers is 5 x 73 x 61 = 22265
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 81/22265
Therefore, the GCF of Fractions 405/365,486/305 is 81/22265
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 365,305 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(365,305) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(365,305) x common factors =5 x 1 = 5
LCM(365,305) = ( 365 × 305 ) / 5
LCM(365,305) = 111325 / 5
LCM(365,305) = 22265
