:1,3,13,23,39,69,299,897
Greatest Common Factor
We found the factors 300,897 . The biggest common factor number is the GCF number.
So the greatest common factor 300,897 is 3.
Lets's calculate LCM of 205,505
5 | 205, 505 |
41, 101 |
∴ So the LCM of the given numbers is 5 x 41 x 101 = 20705
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/20705
Therefore, the GCF of Fractions 300/205,897/505 is 3/20705
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 205,505 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(205,505) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(205,505) x common factors =5 x 1 = 5
LCM(205,505) = ( 205 × 505 ) / 5
LCM(205,505) = 103525 / 5
LCM(205,505) = 20705
