Greatest Common Factor
We found the factors 7,72,68,401 . The biggest common factor number is the GCF number.
So the greatest common factor 7,72,68,401 is 1.
Lets's calculate LCM of 22,10,230,621
2 | 22, 10, 230, 621 |
5 | 11, 5, 115, 621 |
23 | 11, 1, 23, 621 |
11, 1, 1, 27 |
∴ So the LCM of the given numbers is 2 x 5 x 23 x 11 x 1 x 1 x 27 = 68310
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/68310
Therefore, the GCF of Fractions 7/22,72/10,68/230,401/621 is 1/68310
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 22,10,230,621 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(22,10,230,621) = 1
common factors(in case of two or more numbers have common factors) = 460
GCF(22,10,230,621) x common factors =1 x 460 = 460
LCM(22,10,230,621) = ( 22 × 10 × 230 × 621 ) / 460
LCM(22,10,230,621) = 31422600 / 460
LCM(22,10,230,621) = 68310
