Greatest Common Factor
We found the factors 27,232,545 . The biggest common factor number is the GCF number.
So the greatest common factor 27,232,545 is 1.
Lets's calculate LCM of 90,20,831
2 | 90, 20, 831 |
3 | 45, 10, 831 |
5 | 15, 10, 277 |
3, 2, 277 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 3 x 2 x 277 = 49860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/49860
Therefore, the GCF of Fractions 27/90,232/20,545/831 is 1/49860
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 90,20,831 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,20,831) = 1
common factors(in case of two or more numbers have common factors) = 30
GCF(90,20,831) x common factors =1 x 30 = 30
LCM(90,20,831) = ( 90 × 20 × 831 ) / 30
LCM(90,20,831) = 1495800 / 30
LCM(90,20,831) = 49860
