Greatest Common Factor
We found the factors 65,69,74,99 . The biggest common factor number is the GCF number.
So the greatest common factor 65,69,74,99 is 1.
Lets's calculate LCM of 80,39,45,96
2 | 80, 39, 45, 96 |
2 | 40, 39, 45, 48 |
2 | 20, 39, 45, 24 |
2 | 10, 39, 45, 12 |
3 | 5, 39, 45, 6 |
5 | 5, 13, 15, 2 |
1, 13, 3, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 5 x 1 x 13 x 3 x 2 = 18720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18720
Therefore, the GCF of Fractions 65/80,69/39,74/45,99/96 is 1/18720
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 80,39,45,96 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,39,45,96) = 1
common factors(in case of two or more numbers have common factors) = 720
GCF(80,39,45,96) x common factors =1 x 720 = 720
LCM(80,39,45,96) = ( 80 × 39 × 45 × 96 ) / 720
LCM(80,39,45,96) = 13478400 / 720
LCM(80,39,45,96) = 18720
