Given numbers are 159,900,156,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 159,900,156,891 is 61389900.
Find LCM of 159,900,156,891 with Prime Factorization
| 2 | 159, 900, 156, 891 |
| 2 | 159, 450, 78, 891 |
| 3 | 159, 225, 39, 891 |
| 3 | 53, 75, 13, 297 |
| 53, 25, 13, 99 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 53 x 25 x 13 x 99 = 61389900
Therefore, the lowest common multiple of 159,900,156,891 is 61389900.
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.
159 x 900 x 156 x 891 = 19890327600
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.
159 : 1, 3, 53, 159
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,900,156,891, is 3.
Now, the common factors can be found like this.
159:3x 53
900:2x 2x 3x 3x 5x 5
156:2x 2x 3x 13
891:3x 3x 3x 3x 11
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 = 19890327600/(3x108)
LCM = 19890327600/324
LCM = 61389900
Thus, we can understand that the LCM of 159,900,156,891 is 61389900.
