Given numbers are 783,923,338,392,128
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 783,923,338,392,128 is 58926801024.
Find LCM of 783,923,338,392,128 with Prime Factorization
| 2 | 783, 923, 338, 392, 128 |
| 2 | 783, 923, 169, 196, 64 |
| 2 | 783, 923, 169, 98, 32 |
| 13 | 783, 923, 169, 49, 16 |
| 783, 71, 13, 49, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 783 x 71 x 13 x 49 x 16 = 58926801024
Therefore, the lowest common multiple of 783,923,338,392,128 is 58926801024.
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 923 x 338 x 392 x 128 = 12256774612992
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
923 : 1, 13, 71, 923
338 : 1, 2, 13, 26, 169, 338
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,923,338,392,128, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
923:13x 71
338:2x 13x 13
392:2x 2x 2x 7x 7
128:2x 2x 2x 2x 2x 2x 2
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 2x 2x 13 = 208
Therefore, the value for common factors is 208.
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 = 12256774612992/(1x208)
LCM = 12256774612992/208
LCM = 58926801024
Thus, we can understand that the LCM of 783,923,338,392,128 is 58926801024.
