Given numbers are 399,867,495,231,998
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,867,495,231,998 is 18988262370.
Find LCM of 399,867,495,231,998 with Prime Factorization
| 3 | 399, 867, 495, 231, 998 |
| 7 | 133, 289, 165, 77, 998 |
| 11 | 19, 289, 165, 11, 998 |
| 19, 289, 15, 1, 998 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 19 x 289 x 15 x 1 x 998 = 18988262370
Therefore, the lowest common multiple of 399,867,495,231,998 is 18988262370.
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.
399 x 867 x 495 x 231 x 998 = 39476597467230
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
867 : 1, 3, 17, 51, 289, 867
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
231 : 1, 3, 7, 11, 21, 33, 77, 231
998 : 1, 2, 499, 998
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,867,495,231,998, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
867:3x 17x 17
495:3x 3x 5x 11
231:3x 7x 11
998:2x 499
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 3x 7x 11 = 2079
Therefore, the value for common factors is 2079.
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 = 39476597467230/(1x2079)
LCM = 39476597467230/2079
LCM = 18988262370
Thus, we can understand that the LCM of 399,867,495,231,998 is 18988262370.
