Find LCM of 783,844,961,870,387 with Prime Factorization
| 2 | 783, 844, 961, 870, 387 |
| 3 | 783, 422, 961, 435, 387 |
| 3 | 261, 422, 961, 145, 129 |
| 29 | 87, 422, 961, 145, 43 |
| 3, 422, 961, 5, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 29 x 3 x 422 x 961 x 5 x 43 = 136541935980
Therefore, the lowest common multiple of 783,844,961,870,387 is 136541935980.
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.
783 x 844 x 961 x 870 x 387 = 213824671744680
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
844 : 1, 2, 4, 211, 422, 844
961 : 1, 31, 961
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,844,961,870,387, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
844:2x 2x 211
961:31x 31
870:2x 3x 5x 29
387:3x 3x 43
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 3x 3x 29 = 1566
Therefore, the value for common factors is 1566.
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 = 213824671744680/(1x1566)
LCM = 213824671744680/1566
LCM = 136541935980
Thus, we can understand that the LCM of 783,844,961,870,387 is 136541935980.
