Given numbers are 783,995,430,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 783,995,430,731 is 1139022270.
Find LCM of 783,995,430,731 with Prime Factorization
| 5 | 783, 995, 430, 731 |
| 43 | 783, 199, 86, 731 |
| 783, 199, 2, 17 |
Multiply the prime numbers at the bottom and the left side.
5 x 43 x 783 x 199 x 2 x 17 = 1139022270
Therefore, the lowest common multiple of 783,995,430,731 is 1139022270.
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.
783 x 995 x 430 x 731 = 244889788050
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
995 : 1, 5, 199, 995
430 : 1, 2, 5, 10, 43, 86, 215, 430
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,995,430,731, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
995:5x 199
430:2x 5x 43
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.
5x 43 = 215
Therefore, the value for common factors is 215.
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 = 244889788050/(1x215)
LCM = 244889788050/215
LCM = 1139022270
Thus, we can understand that the LCM of 783,995,430,731 is 1139022270.
