The LCM of 961,702,864,876 is 787958496.
Find LCM of 961,702,864,876 with Prime Factorization
| 2 | 961, 702, 864, 876 |
| 2 | 961, 351, 432, 438 |
| 3 | 961, 351, 216, 219 |
| 3 | 961, 117, 72, 73 |
| 3 | 961, 39, 24, 73 |
| 961, 13, 8, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 961 x 13 x 8 x 73 = 787958496
Therefore, the lowest common multiple of 961,702,864,876 is 787958496.
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.
961 x 702 x 864 x 876 = 510597105408
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.
961 : 1, 31, 961
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,702,864,876, is 1.
Now, the common factors can be found like this.
961:31x 31
702:2x 3x 3x 3x 13
864:2x 2x 2x 2x 2x 3x 3x 3
876:2x 2x 3x 73
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 3x 3x 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 510597105408/(1x648)
LCM = 510597105408/648
LCM = 787958496
Thus, we can understand that the LCM of 961,702,864,876 is 787958496.
