Find LCM of 638,176,208,333,845 with Prime Factorization
| 2 | 638, 176, 208, 333, 845 |
| 2 | 319, 88, 104, 333, 845 |
| 2 | 319, 44, 52, 333, 845 |
| 2 | 319, 22, 26, 333, 845 |
| 11 | 319, 11, 13, 333, 845 |
| 13 | 29, 1, 13, 333, 845 |
| 29, 1, 1, 333, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 11 x 13 x 29 x 1 x 1 x 333 x 65 = 1436189040
Therefore, the lowest common multiple of 638,176,208,333,845 is 1436189040.
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 176 x 208 x 333 x 845 = 6572001047040
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
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
333 : 1, 3, 9, 37, 111, 333
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,176,208,333,845, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
176:2x 2x 2x 2x 11
208:2x 2x 2x 2x 13
333:3x 3x 37
845:5x 13x 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 11x 13 = 4576
Therefore, the value for common factors is 4576.
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 = 6572001047040/(1x4576)
LCM = 6572001047040/4576
LCM = 1436189040
Thus, we can understand that the LCM of 638,176,208,333,845 is 1436189040.
