Given numbers are 428,382,886,400,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,382,886,400,155 is 112264528400.
Find LCM of 428,382,886,400,155 with Prime Factorization
| 2 | 428, 382, 886, 400, 155 |
| 2 | 214, 191, 443, 200, 155 |
| 5 | 107, 191, 443, 100, 155 |
| 107, 191, 443, 20, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 107 x 191 x 443 x 20 x 31 = 112264528400
Therefore, the lowest common multiple of 428,382,886,400,155 is 112264528400.
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.
428 x 382 x 886 x 400 x 155 = 8981162272000
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.
428 : 1, 2, 4, 107, 214, 428
382 : 1, 2, 191, 382
886 : 1, 2, 443, 886
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,382,886,400,155, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
382:2x 191
886:2x 443
400:2x 2x 2x 2x 5x 5
155:5x 31
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 5 = 80
Therefore, the value for common factors is 80.
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 = 8981162272000/(1x80)
LCM = 8981162272000/80
LCM = 112264528400
Thus, we can understand that the LCM of 428,382,886,400,155 is 112264528400.
