:1,3,5,15,59,177,295,885
Greatest Common Factor
We found the factors 720,885 . The biggest common factor number is the GCF number.
So the greatest common factor 720,885 is 15.
Lets's calculate LCM of 810,130
2 | 810, 130 |
5 | 405, 65 |
81, 13 |
∴ So the LCM of the given numbers is 2 x 5 x 81 x 13 = 10530
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/10530
Therefore, the GCF of Fractions 720/810,885/130 is 15/10530
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 810,130 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(810,130) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(810,130) x common factors =10 x 1 = 10
LCM(810,130) = ( 810 × 130 ) / 10
LCM(810,130) = 105300 / 10
LCM(810,130) = 10530
