Find LCM of 464,816,638,396 with Prime Factorization
| 2 | 464, 816, 638, 396 |
| 2 | 232, 408, 319, 198 |
| 2 | 116, 204, 319, 99 |
| 2 | 58, 102, 319, 99 |
| 3 | 29, 51, 319, 99 |
| 11 | 29, 17, 319, 33 |
| 29 | 29, 17, 29, 3 |
| 1, 17, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 11 x 29 x 1 x 17 x 1 x 3 = 780912
Therefore, the lowest common multiple of 464,816,638,396 is 780912.
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.
464 x 816 x 638 x 396 = 95658596352
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.
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
638 : 1, 2, 11, 22, 29, 58, 319, 638
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 464,816,638,396, is 2.
Now, the common factors can be found like this.
464:2x 2x 2x 2x 29
816:2x 2x 2x 2x 3x 17
638:2x 11x 29
396:2x 2x 3x 3x 11
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 11x 29 = 61248
Therefore, the value for common factors is 61248.
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 = 95658596352/(2x61248)
LCM = 95658596352/122496
LCM = 780912
Thus, we can understand that the LCM of 464,816,638,396 is 780912.
