Given numbers are 396,900,825
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,900,825 is 9900.
Find LCM of 396,900,825 with Prime Factorization
| 2 | 396, 900, 825 |
| 2 | 198, 450, 825 |
| 3 | 99, 225, 825 |
| 3 | 33, 75, 275 |
| 5 | 11, 25, 275 |
| 5 | 11, 5, 55 |
| 11 | 11, 1, 11 |
| 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 5 x 11 x 1 x 1 x 1 = 9900
Therefore, the lowest common multiple of 396,900,825 is 9900.
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.
396 x 900 x 825 = 294030000
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
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
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,900,825, is 3.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
900:2x 2x 3x 3x 5x 5
825:3x 5x 5x 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 5x 5x 11 = 9900
Therefore, the value for common factors is 9900.
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 = 294030000/(3x9900)
LCM = 294030000/29700
LCM = 9900
Thus, we can understand that the LCM of 396,900,825 is 9900.
