We found the factors 117,990 . The biggest common factor number is the GCF number.
So the greatest common factor 117,990 is 9.
Lets's calculate LCM of 864,616
2 | 864, 616 |
2 | 432, 308 |
2 | 216, 154 |
108, 77 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 108 x 77 = 66528
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/66528
Therefore, the GCF of Fractions 117/864,990/616 is 9/66528
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 864,616 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(864,616) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(864,616) x common factors =8 x 1 = 8
LCM(864,616) = ( 864 × 616 ) / 8
LCM(864,616) = 532224 / 8
LCM(864,616) = 66528
