Given numbers are 405,645,299,402,365
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,645,299,402,365 is 50935705470.
Find LCM of 405,645,299,402,365 with Prime Factorization
| 3 | 405, 645, 299, 402, 365 |
| 5 | 135, 215, 299, 134, 365 |
| 27, 43, 299, 134, 73 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 27 x 43 x 299 x 134 x 73 = 50935705470
Therefore, the lowest common multiple of 405,645,299,402,365 is 50935705470.
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.
405 x 645 x 299 x 402 x 365 = 11460533730750
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
645 : 1, 3, 5, 15, 43, 129, 215, 645
299 : 1, 13, 23, 299
402 : 1, 2, 3, 6, 67, 134, 201, 402
365 : 1, 5, 73, 365
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,645,299,402,365, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
645:3x 5x 43
299:13x 23
402:2x 3x 67
365:5x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5 = 225
Therefore, the value for common factors is 225.
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 = 11460533730750/(1x225)
LCM = 11460533730750/225
LCM = 50935705470
Thus, we can understand that the LCM of 405,645,299,402,365 is 50935705470.
