Given numbers are 396,624,667,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,624,667,423 is 645538608.
Find LCM of 396,624,667,423 with Prime Factorization
| 2 | 396, 624, 667, 423 |
| 2 | 198, 312, 667, 423 |
| 3 | 99, 156, 667, 423 |
| 3 | 33, 52, 667, 141 |
| 11, 52, 667, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 52 x 667 x 47 = 645538608
Therefore, the lowest common multiple of 396,624,667,423 is 645538608.
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 624 x 667 x 423 = 69718169664
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
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
667 : 1, 23, 29, 667
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,624,667,423, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
624:2x 2x 2x 2x 3x 13
667:23x 29
423:3x 3x 47
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 69718169664/(1x108)
LCM = 69718169664/108
LCM = 645538608
Thus, we can understand that the LCM of 396,624,667,423 is 645538608.
