Given numbers are 164,855,786,621,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 164,855,786,621,406 is 257292061740.
Find LCM of 164,855,786,621,406 with Prime Factorization
| 2 | 164, 855, 786, 621, 406 |
| 3 | 82, 855, 393, 621, 203 |
| 3 | 82, 285, 131, 207, 203 |
| 82, 95, 131, 69, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 82 x 95 x 131 x 69 x 203 = 257292061740
Therefore, the lowest common multiple of 164,855,786,621,406 is 257292061740.
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.
164 x 855 x 786 x 621 x 406 = 27787542667920
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.
164 : 1, 2, 4, 41, 82, 164
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
786 : 1, 2, 3, 6, 131, 262, 393, 786
621 : 1, 3, 9, 23, 27, 69, 207, 621
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 164,855,786,621,406, is 1.
Now, the common factors can be found like this.
164:2x 2x 41
855:3x 3x 5x 19
786:2x 3x 131
621:3x 3x 3x 23
406:2x 7x 29
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 3 = 108
Therefore, the value for common factors is 108.
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 = 27787542667920/(1x108)
LCM = 27787542667920/108
LCM = 257292061740
Thus, we can understand that the LCM of 164,855,786,621,406 is 257292061740.
