Find LCM of 907,834,442,663,391 with Prime Factorization
| 2 | 907, 834, 442, 663, 391 |
| 3 | 907, 417, 221, 663, 391 |
| 13 | 907, 139, 221, 221, 391 |
| 17 | 907, 139, 17, 17, 391 |
| 907, 139, 1, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 907 x 139 x 1 x 1 x 23 = 3844974354
Therefore, the lowest common multiple of 907,834,442,663,391 is 3844974354.
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.
907 x 834 x 442 x 663 x 391 = 86673411887868
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.
907 : 1, 907
834 : 1, 2, 3, 6, 139, 278, 417, 834
442 : 1, 2, 13, 17, 26, 34, 221, 442
663 : 1, 3, 13, 17, 39, 51, 221, 663
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 907,834,442,663,391, is 1.
Now, the common factors can be found like this.
907:907
834:2x 3x 139
442:2x 13x 17
663:3x 13x 17
391:17x 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 3x 13x 17x 17 = 22542
Therefore, the value for common factors is 22542.
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 = 86673411887868/(1x22542)
LCM = 86673411887868/22542
LCM = 3844974354
Thus, we can understand that the LCM of 907,834,442,663,391 is 3844974354.
