Greatest Common Factor
We found the factors 476,403,805 . The biggest common factor number is the GCF number.
So the greatest common factor 476,403,805 is 1.
Lets's calculate LCM of 18,72,286
2 | 18, 72, 286 |
3 | 9, 36, 143 |
3 | 3, 12, 143 |
1, 4, 143 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 1 x 4 x 143 = 10296
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10296
Therefore, the GCF of Fractions 476/18,403/72,805/286 is 1/10296
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 18,72,286 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,72,286) = 2
common factors(in case of two or more numbers have common factors) = 18
GCF(18,72,286) x common factors =2 x 18 = 36
LCM(18,72,286) = ( 18 × 72 × 286 ) / 36
LCM(18,72,286) = 370656 / 36
LCM(18,72,286) = 10296
