Find LCM of 768,861,943,964,129 with Prime Factorization
| 2 | 768, 861, 943, 964, 129 |
| 2 | 384, 861, 943, 482, 129 |
| 3 | 192, 861, 943, 241, 129 |
| 41 | 64, 287, 943, 241, 43 |
| 64, 7, 23, 241, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 41 x 64 x 7 x 23 x 241 x 43 = 52535933184
Therefore, the lowest common multiple of 768,861,943,964,129 is 52535933184.
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.
768 x 861 x 943 x 964 x 129 = 77543037379584
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
861 : 1, 3, 7, 21, 41, 123, 287, 861
943 : 1, 23, 41, 943
964 : 1, 2, 4, 241, 482, 964
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,861,943,964,129, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
861:3x 7x 41
943:23x 41
964:2x 2x 241
129:3x 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 2x 3x 3x 41 = 1476
Therefore, the value for common factors is 1476.
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 = 77543037379584/(1x1476)
LCM = 77543037379584/1476
LCM = 52535933184
Thus, we can understand that the LCM of 768,861,943,964,129 is 52535933184.
