Given numbers are 418,561,957,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,561,957,129 is 26583546.
Find LCM of 418,561,957,129 with Prime Factorization
| 3 | 418, 561, 957, 129 |
| 11 | 418, 187, 319, 43 |
| 38, 17, 29, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 38 x 17 x 29 x 43 = 26583546
Therefore, the lowest common multiple of 418,561,957,129 is 26583546.
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.
418 x 561 x 957 x 129 = 28949481594
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
561 : 1, 3, 11, 17, 33, 51, 187, 561
957 : 1, 3, 11, 29, 33, 87, 319, 957
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,561,957,129, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
561:3x 11x 17
957:3x 11x 29
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.
3x 3x 11x 11 = 1089
Therefore, the value for common factors is 1089.
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 = 28949481594/(1x1089)
LCM = 28949481594/1089
LCM = 26583546
Thus, we can understand that the LCM of 418,561,957,129 is 26583546.
