Given numbers are 159,225,990,685,872
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 159,225,990,685,872 is 15670690200.
Find LCM of 159,225,990,685,872 with Prime Factorization
| 2 | 159, 225, 990, 685, 872 |
| 3 | 159, 225, 495, 685, 436 |
| 3 | 53, 75, 165, 685, 436 |
| 5 | 53, 25, 55, 685, 436 |
| 53, 5, 11, 137, 436 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 53 x 5 x 11 x 137 x 436 = 15670690200
Therefore, the lowest common multiple of 159,225,990,685,872 is 15670690200.
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 225 x 990 x 685 x 872 = 21155431770000
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
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
685 : 1, 5, 137, 685
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,225,990,685,872, is 1.
Now, the common factors can be found like this.
159:3x 53
225:3x 3x 5x 5
990:2x 3x 3x 5x 11
685:5x 137
872:2x 2x 2x 109
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 5x 5 = 1350
Therefore, the value for common factors is 1350.
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 = 21155431770000/(1x1350)
LCM = 21155431770000/1350
LCM = 15670690200
Thus, we can understand that the LCM of 159,225,990,685,872 is 15670690200.
