Given numbers are 400,400,384,484
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,400,384,484 is 1161600.
Find LCM of 400,400,384,484 with Prime Factorization
| 2 | 400, 400, 384, 484 |
| 2 | 200, 200, 192, 242 |
| 2 | 100, 100, 96, 121 |
| 2 | 50, 50, 48, 121 |
| 5 | 25, 25, 24, 121 |
| 5 | 5, 5, 24, 121 |
| 1, 1, 24, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 5 x 1 x 1 x 24 x 121 = 1161600
Therefore, the lowest common multiple of 400,400,384,484 is 1161600.
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.
400 x 400 x 384 x 484 = 29736960000
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,400,384,484, is 4.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
400:2x 2x 2x 2x 5x 5
384:2x 2x 2x 2x 2x 2x 2x 3
484:2x 2x 11x 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 2x 2x 2x 2x 2x 2x 5x 5 = 6400
Therefore, the value for common factors is 6400.
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 = 29736960000/(4x6400)
LCM = 29736960000/25600
LCM = 1161600
Thus, we can understand that the LCM of 400,400,384,484 is 1161600.
