:1,2,5,10,31,62,155,310
Greatest Common Factor
We found the factors 670,310 . The biggest common factor number is the GCF number.
So the greatest common factor 670,310 is 10.
Lets's calculate LCM of 655,917
131 | 655, 917 |
5, 7 |
∴ So the LCM of the given numbers is 131 x 5 x 7 = 4585
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/4585
Therefore, the GCF of Fractions 670/655,310/917 is 10/4585
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 655,917 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(655,917) = 131
common factors(in case of two or more numbers have common factors) = 1
GCF(655,917) x common factors =131 x 1 = 131
LCM(655,917) = ( 655 × 917 ) / 131
LCM(655,917) = 600635 / 131
LCM(655,917) = 4585
