Find LCM of 791,289,876,221,858 with Prime Factorization
| 2 | 791, 289, 876, 221, 858 |
| 3 | 791, 289, 438, 221, 429 |
| 13 | 791, 289, 146, 221, 143 |
| 17 | 791, 289, 146, 17, 11 |
| 791, 1, 146, 17, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 791 x 1 x 146 x 17 x 11 = 28636139532
Therefore, the lowest common multiple of 791,289,876,221,858 is 28636139532.
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.
791 x 289 x 876 x 221 x 858 = 37971521019432
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.
791 : 1, 7, 113, 791
289 : 1, 17, 289
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
221 : 1, 13, 17, 221
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,289,876,221,858, is 1.
Now, the common factors can be found like this.
791:7x 113
289:17x 17
876:2x 2x 3x 73
221:13x 17
858:2x 3x 11x 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 3x 13x 17 = 1326
Therefore, the value for common factors is 1326.
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 = 37971521019432/(1x1326)
LCM = 37971521019432/1326
LCM = 28636139532
Thus, we can understand that the LCM of 791,289,876,221,858 is 28636139532.
