Given numbers are 173,261,786,846,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 173,261,786,846,561 is 103974625854.
Find LCM of 173,261,786,846,561 with Prime Factorization
| 2 | 173, 261, 786, 846, 561 |
| 3 | 173, 261, 393, 423, 561 |
| 3 | 173, 87, 131, 141, 187 |
| 173, 29, 131, 47, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 173 x 29 x 131 x 47 x 187 = 103974625854
Therefore, the lowest common multiple of 173,261,786,846,561 is 103974625854.
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.
173 x 261 x 786 x 846 x 561 = 16843889388348
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.
173 : 1, 173
261 : 1, 3, 9, 29, 87, 261
786 : 1, 2, 3, 6, 131, 262, 393, 786
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,261,786,846,561, is 1.
Now, the common factors can be found like this.
173:173
261:3x 3x 29
786:2x 3x 131
846:2x 3x 3x 47
561:3x 11x 17
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 3 = 162
Therefore, the value for common factors is 162.
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 = 16843889388348/(1x162)
LCM = 16843889388348/162
LCM = 103974625854
Thus, we can understand that the LCM of 173,261,786,846,561 is 103974625854.
