Given numbers are 456,384,405,854
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 456,384,405,854 is 420577920.
Find LCM of 456,384,405,854 with Prime Factorization
| 2 | 456, 384, 405, 854 |
| 2 | 228, 192, 405, 427 |
| 2 | 114, 96, 405, 427 |
| 3 | 57, 48, 405, 427 |
| 19, 16, 135, 427 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 16 x 135 x 427 = 420577920
Therefore, the lowest common multiple of 456,384,405,854 is 420577920.
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.
456 x 384 x 405 x 854 = 60563220480
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
854 : 1, 2, 7, 14, 61, 122, 427, 854
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,384,405,854, is 1.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
384:2x 2x 2x 2x 2x 2x 2x 3
405:3x 3x 3x 3x 5
854:2x 7x 61
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 60563220480/(1x144)
LCM = 60563220480/144
LCM = 420577920
Thus, we can understand that the LCM of 456,384,405,854 is 420577920.
