Given numbers are 180,418,231,388,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 180,418,231,388,641 is 16373691180.
Find LCM of 180,418,231,388,641 with Prime Factorization
| 2 | 180, 418, 231, 388, 641 |
| 2 | 90, 209, 231, 194, 641 |
| 3 | 45, 209, 231, 97, 641 |
| 11 | 15, 209, 77, 97, 641 |
| 15, 19, 7, 97, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 15 x 19 x 7 x 97 x 641 = 16373691180
Therefore, the lowest common multiple of 180,418,231,388,641 is 16373691180.
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.
180 x 418 x 231 x 388 x 641 = 4322654471520
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
418 : 1, 2, 11, 19, 22, 38, 209, 418
231 : 1, 3, 7, 11, 21, 33, 77, 231
388 : 1, 2, 4, 97, 194, 388
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,418,231,388,641, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
418:2x 11x 19
231:3x 7x 11
388:2x 2x 97
641:641
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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 4322654471520/(1x264)
LCM = 4322654471520/264
LCM = 16373691180
Thus, we can understand that the LCM of 180,418,231,388,641 is 16373691180.
