Greatest Common Factor
We found the factors 17,30,772 . The biggest common factor number is the GCF number.
So the greatest common factor 17,30,772 is 1.
Lets's calculate LCM of 180,448,958
2 | 180, 448, 958 |
2 | 90, 224, 479 |
45, 112, 479 |
∴ So the LCM of the given numbers is 2 x 2 x 45 x 112 x 479 = 9656640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9656640
Therefore, the GCF of Fractions 17/180,30/448,772/958 is 1/9656640
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 180,448,958 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(180,448,958) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(180,448,958) x common factors =2 x 4 = 8
LCM(180,448,958) = ( 180 × 448 × 958 ) / 8
LCM(180,448,958) = 77253120 / 8
LCM(180,448,958) = 9656640
