1,2,3,4,5,6,8,10,12,15,16,20,24,30,32,40,48,60,64,80,96,120,160,192,240,320,480,960
Greatest Common Factor
We found the factors 81,183,960 . The biggest common factor number is the GCF number.
So the greatest common factor 81,183,960 is 3.
Lets's calculate LCM of 70,15,426
2 | 70, 15, 426 |
3 | 35, 15, 213 |
5 | 35, 5, 71 |
7, 1, 71 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 1 x 71 = 14910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/14910
Therefore, the GCF of Fractions 81/70,183/15,960/426 is 3/14910
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 70,15,426 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,15,426) = 1
common factors(in case of two or more numbers have common factors) = 30
GCF(70,15,426) x common factors =1 x 30 = 30
LCM(70,15,426) = ( 70 × 15 × 426 ) / 30
LCM(70,15,426) = 447300 / 30
LCM(70,15,426) = 14910
