Given numbers are 426,786,309,721,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 426,786,309,721,489 is 6558488538.
Find LCM of 426,786,309,721,489 with Prime Factorization
| 2 | 426, 786, 309, 721, 489 |
| 3 | 213, 393, 309, 721, 489 |
| 103 | 71, 131, 103, 721, 163 |
| 71, 131, 1, 7, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 71 x 131 x 1 x 7 x 163 = 6558488538
Therefore, the lowest common multiple of 426,786,309,721,489 is 6558488538.
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.
426 x 786 x 309 x 721 x 489 = 36478313248356
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.
426 : 1, 2, 3, 6, 71, 142, 213, 426
786 : 1, 2, 3, 6, 131, 262, 393, 786
309 : 1, 3, 103, 309
721 : 1, 7, 103, 721
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,786,309,721,489, is 1.
Now, the common factors can be found like this.
426:2x 3x 71
786:2x 3x 131
309:3x 103
721:7x 103
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 3x 3x 3x 103 = 5562
Therefore, the value for common factors is 5562.
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 = 36478313248356/(1x5562)
LCM = 36478313248356/5562
LCM = 6558488538
Thus, we can understand that the LCM of 426,786,309,721,489 is 6558488538.
