Given numbers are 468,205,581,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 468,205,581,455 is 55741140.
Find LCM of 468,205,581,455 with Prime Factorization
| 5 | 468, 205, 581, 455 |
| 7 | 468, 41, 581, 91 |
| 13 | 468, 41, 83, 13 |
| 36, 41, 83, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 13 x 36 x 41 x 83 x 1 = 55741140
Therefore, the lowest common multiple of 468,205,581,455 is 55741140.
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.
468 x 205 x 581 x 455 = 25362218700
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
205 : 1, 5, 41, 205
581 : 1, 7, 83, 581
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,205,581,455, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
205:5x 41
581:7x 83
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 13 = 455
Therefore, the value for common factors is 455.
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 = 25362218700/(1x455)
LCM = 25362218700/455
LCM = 55741140
Thus, we can understand that the LCM of 468,205,581,455 is 55741140.
