Given numbers are 391,814,172,901,559
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,814,172,901,559 is 18859007596.
Find LCM of 391,814,172,901,559 with Prime Factorization
| 2 | 391, 814, 172, 901, 559 |
| 17 | 391, 407, 86, 901, 559 |
| 43 | 23, 407, 86, 53, 559 |
| 23, 407, 2, 53, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 43 x 23 x 407 x 2 x 53 x 13 = 18859007596
Therefore, the lowest common multiple of 391,814,172,901,559 is 18859007596.
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.
391 x 814 x 172 x 901 x 559 = 27571869105352
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.
391 : 1, 17, 23, 391
814 : 1, 2, 11, 22, 37, 74, 407, 814
172 : 1, 2, 4, 43, 86, 172
901 : 1, 17, 53, 901
559 : 1, 13, 43, 559
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,814,172,901,559, is 1.
Now, the common factors can be found like this.
391:17x 23
814:2x 11x 37
172:2x 2x 43
901:17x 53
559:13x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 43 = 1462
Therefore, the value for common factors is 1462.
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 = 27571869105352/(1x1462)
LCM = 27571869105352/1462
LCM = 18859007596
Thus, we can understand that the LCM of 391,814,172,901,559 is 18859007596.
