Given numbers are 469,489,481,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 469,489,481,815 is 551565105.
Find LCM of 469,489,481,815 with Prime Factorization
| 163 | 469, 489, 481, 815 |
| 469, 3, 481, 5 |
Multiply the prime numbers at the bottom and the left side.
163 x 469 x 3 x 481 x 5 = 551565105
Therefore, the lowest common multiple of 469,489,481,815 is 551565105.
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.
469 x 489 x 481 x 815 = 89905112115
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.
469 : 1, 7, 67, 469
489 : 1, 3, 163, 489
481 : 1, 13, 37, 481
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 469,489,481,815, is 1.
Now, the common factors can be found like this.
469:7x 67
489:3x 163
481:13x 37
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
163 = 163
Therefore, the value for common factors is 163.
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 = 89905112115/(1x163)
LCM = 89905112115/163
LCM = 551565105
Thus, we can understand that the LCM of 469,489,481,815 is 551565105.
