Find LCM of 638,396,306,736,299 with Prime Factorization
| 2 | 638, 396, 306, 736, 299 |
| 2 | 319, 198, 153, 368, 299 |
| 3 | 319, 99, 153, 184, 299 |
| 3 | 319, 33, 51, 184, 299 |
| 11 | 319, 11, 17, 184, 299 |
| 23 | 29, 1, 17, 184, 299 |
| 29, 1, 17, 8, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 23 x 29 x 1 x 17 x 8 x 13 = 466985376
Therefore, the lowest common multiple of 638,396,306,736,299 is 466985376.
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.
638 x 396 x 306 x 736 x 299 = 17013211218432
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.
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
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
299 : 1, 13, 23, 299
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,396,306,736,299, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
396:2x 2x 3x 3x 11
306:2x 3x 3x 17
736:2x 2x 2x 2x 2x 23
299:13x 23
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 3x 3x 11x 23 = 36432
Therefore, the value for common factors is 36432.
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 = 17013211218432/(1x36432)
LCM = 17013211218432/36432
LCM = 466985376
Thus, we can understand that the LCM of 638,396,306,736,299 is 466985376.
