Given numbers are 405,693,382,340,487
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,693,382,340,487 is 197249989860.
Find LCM of 405,693,382,340,487 with Prime Factorization
| 2 | 405, 693, 382, 340, 487 |
| 3 | 405, 693, 191, 170, 487 |
| 3 | 135, 231, 191, 170, 487 |
| 5 | 45, 77, 191, 170, 487 |
| 9, 77, 191, 34, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 9 x 77 x 191 x 34 x 487 = 197249989860
Therefore, the lowest common multiple of 405,693,382,340,487 is 197249989860.
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 693 x 382 x 340 x 487 = 17752499087400
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
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
382 : 1, 2, 191, 382
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
487 : 1, 487
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,693,382,340,487, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
693:3x 3x 7x 11
382:2x 191
340:2x 2x 5x 17
487:487
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 17752499087400/(1x90)
LCM = 17752499087400/90
LCM = 197249989860
Thus, we can understand that the LCM of 405,693,382,340,487 is 197249989860.
