Given numbers are 153,783,725,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 153,783,725,731 is 14309325.
Find LCM of 153,783,725,731 with Prime Factorization
| 3 | 153, 783, 725, 731 |
| 3 | 51, 261, 725, 731 |
| 17 | 17, 87, 725, 731 |
| 29 | 1, 87, 725, 43 |
| 1, 3, 25, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 29 x 1 x 3 x 25 x 43 = 14309325
Therefore, the lowest common multiple of 153,783,725,731 is 14309325.
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.
153 x 783 x 725 x 731 = 63490475025
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.
153 : 1, 3, 9, 17, 51, 153
783 : 1, 3, 9, 27, 29, 87, 261, 783
725 : 1, 5, 25, 29, 145, 725
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,783,725,731, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
783:3x 3x 3x 29
725:5x 5x 29
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 17x 29 = 4437
Therefore, the value for common factors is 4437.
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 = 63490475025/(1x4437)
LCM = 63490475025/4437
LCM = 14309325
Thus, we can understand that the LCM of 153,783,725,731 is 14309325.
