Greatest Common Factor
We found the factors 918,732,649 . The biggest common factor number is the GCF number.
So the greatest common factor 918,732,649 is 1.
Lets's calculate LCM of 80,96,72
2 | 80, 96, 72 |
2 | 40, 48, 36 |
2 | 20, 24, 18 |
2 | 10, 12, 9 |
3 | 5, 6, 9 |
5, 2, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 5 x 2 x 3 = 1440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1440
Therefore, the GCF of Fractions 918/80,732/96,649/72 is 1/1440
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 80,96,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,96,72) = 8
common factors(in case of two or more numbers have common factors) = 48
GCF(80,96,72) x common factors =8 x 48 = 384
LCM(80,96,72) = ( 80 × 96 × 72 ) / 384
LCM(80,96,72) = 552960 / 384
LCM(80,96,72) = 1440
