Given numbers are 129,391,943,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 129,391,943,656 is 33087984.
Find LCM of 129,391,943,656 with Prime Factorization
| 23 | 129, 391, 943, 656 |
| 41 | 129, 17, 41, 656 |
| 129, 17, 1, 16 |
Multiply the prime numbers at the bottom and the left side.
23 x 41 x 129 x 17 x 1 x 16 = 33087984
Therefore, the lowest common multiple of 129,391,943,656 is 33087984.
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.
129 x 391 x 943 x 656 = 31201968912
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.
129 : 1, 3, 43, 129
391 : 1, 17, 23, 391
943 : 1, 23, 41, 943
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,391,943,656, is 1.
Now, the common factors can be found like this.
129:3x 43
391:17x 23
943:23x 41
656:2x 2x 2x 2x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 41 = 943
Therefore, the value for common factors is 943.
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 = 31201968912/(1x943)
LCM = 31201968912/943
LCM = 33087984
Thus, we can understand that the LCM of 129,391,943,656 is 33087984.
