Given numbers are 484,391,605,437
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 484,391,605,437 is 17978180.
Find LCM of 484,391,605,437 with Prime Factorization
| 11 | 484, 391, 605, 437 |
| 11 | 44, 391, 55, 437 |
| 23 | 4, 391, 5, 437 |
| 4, 17, 5, 19 |
Multiply the prime numbers at the bottom and the left side.
11 x 11 x 23 x 4 x 17 x 5 x 19 = 17978180
Therefore, the lowest common multiple of 484,391,605,437 is 17978180.
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.
484 x 391 x 605 x 437 = 50033274940
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.
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
391 : 1, 17, 23, 391
605 : 1, 5, 11, 55, 121, 605
437 : 1, 19, 23, 437
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,391,605,437, is 1.
Now, the common factors can be found like this.
484:2x 2x 11x 11
391:17x 23
605:5x 11x 11
437:19x 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 11x 23 = 2783
Therefore, the value for common factors is 2783.
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 = 50033274940/(1x2783)
LCM = 50033274940/2783
LCM = 17978180
Thus, we can understand that the LCM of 484,391,605,437 is 17978180.
