Given numbers are 233,720,972,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 233,720,972,489 is 738311760.
Find LCM of 233,720,972,489 with Prime Factorization
| 2 | 233, 720, 972, 489 |
| 2 | 233, 360, 486, 489 |
| 3 | 233, 180, 243, 489 |
| 3 | 233, 60, 81, 163 |
| 233, 20, 27, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 233 x 20 x 27 x 163 = 738311760
Therefore, the lowest common multiple of 233,720,972,489 is 738311760.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
233 x 720 x 972 x 489 = 79737670080
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
233 : 1, 233
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 233,720,972,489, is 1.
Now, the common factors can be found like this.
233:233
720:2x 2x 2x 2x 3x 3x 5
972:2x 2x 3x 3x 3x 3x 3
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3 = 108
Therefore, the value for common factors is 108.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 79737670080/(1x108)
LCM = 79737670080/108
LCM = 738311760
Thus, we can understand that the LCM of 233,720,972,489 is 738311760.
