Given numbers are 396,155,418,961,461
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,155,418,961,461 is 16666450020.
Find LCM of 396,155,418,961,461 with Prime Factorization
| 2 | 396, 155, 418, 961, 461 |
| 11 | 198, 155, 209, 961, 461 |
| 31 | 18, 155, 19, 961, 461 |
| 18, 5, 19, 31, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 31 x 18 x 5 x 19 x 31 x 461 = 16666450020
Therefore, the lowest common multiple of 396,155,418,961,461 is 16666450020.
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.
396 x 155 x 418 x 961 x 461 = 11366518913640
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
155 : 1, 5, 31, 155
418 : 1, 2, 11, 19, 22, 38, 209, 418
961 : 1, 31, 961
461 : 1, 461
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,155,418,961,461, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
155:5x 31
418:2x 11x 19
961:31x 31
461:461
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 31 = 682
Therefore, the value for common factors is 682.
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 = 11366518913640/(1x682)
LCM = 11366518913640/682
LCM = 16666450020
Thus, we can understand that the LCM of 396,155,418,961,461 is 16666450020.
