Greatest Common Factor
We found the factors 31,74,431 . The biggest common factor number is the GCF number.
So the greatest common factor 31,74,431 is 1.
Lets's calculate LCM of 324,183,972
2 | 324, 183, 972 |
2 | 162, 183, 486 |
3 | 81, 183, 243 |
3 | 27, 61, 81 |
3 | 9, 61, 27 |
3 | 3, 61, 9 |
1, 61, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 3 x 3 x 1 x 61 x 3 = 59292
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/59292
Therefore, the GCF of Fractions 31/324,74/183,431/972 is 1/59292
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 324,183,972 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(324,183,972) = 3
common factors(in case of two or more numbers have common factors) = 324
GCF(324,183,972) x common factors =3 x 324 = 972
LCM(324,183,972) = ( 324 × 183 × 972 ) / 972
LCM(324,183,972) = 57631824 / 972
LCM(324,183,972) = 59292
