Given numbers are 506,451,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 506,451,391 is 352682.
Find LCM of 506,451,391 with Prime Factorization
| 11 | 506, 451, 391 |
| 23 | 46, 41, 391 |
| 2, 41, 17 |
Multiply the prime numbers at the bottom and the left side.
11 x 23 x 2 x 41 x 17 = 352682
Therefore, the lowest common multiple of 506,451,391 is 352682.
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.
506 x 451 x 391 = 89228546
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.
506 : 1, 2, 11, 22, 23, 46, 253, 506
451 : 1, 11, 41, 451
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 506,451,391, is 1.
Now, the common factors can be found like this.
506:2x 11x 23
451:11x 41
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 23 = 253
Therefore, the value for common factors is 253.
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 = 89228546/(1x253)
LCM = 89228546/253
LCM = 352682
Thus, we can understand that the LCM of 506,451,391 is 352682.
