Find LCM of 468,704,780,172,585 with Prime Factorization
| 2 | 468, 704, 780, 172, 585 |
| 2 | 234, 352, 390, 86, 585 |
| 3 | 117, 176, 195, 43, 585 |
| 3 | 39, 176, 65, 43, 195 |
| 5 | 13, 176, 65, 43, 65 |
| 13 | 13, 176, 13, 43, 13 |
| 1, 176, 1, 43, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 13 x 1 x 176 x 1 x 43 x 1 = 17709120
Therefore, the lowest common multiple of 468,704,780,172,585 is 17709120.
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 704 x 780 x 172 x 585 = 25858148659200
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
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
172 : 1, 2, 4, 43, 86, 172
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,704,780,172,585, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
704:2x 2x 2x 2x 2x 2x 11
780:2x 2x 3x 5x 13
172:2x 2x 43
585:3x 3x 5x 13
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 2x 2x 2x 2x 3x 3x 3x 5x 13x 13 = 1460160
Therefore, the value for common factors is 1460160.
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 = 25858148659200/(1x1460160)
LCM = 25858148659200/1460160
LCM = 17709120
Thus, we can understand that the LCM of 468,704,780,172,585 is 17709120.
