Given numbers are 388,668,982,888,982
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 388,668,982,888,982 is 7062893592.
Find LCM of 388,668,982,888,982 with Prime Factorization
| 2 | 388, 668, 982, 888, 982 |
| 2 | 194, 334, 491, 444, 491 |
| 491 | 97, 167, 491, 222, 491 |
| 97, 167, 1, 222, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 491 x 97 x 167 x 1 x 222 x 1 = 7062893592
Therefore, the lowest common multiple of 388,668,982,888,982 is 7062893592.
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.
388 x 668 x 982 x 888 x 982 = 221944368235008
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.
388 : 1, 2, 4, 97, 194, 388
668 : 1, 2, 4, 167, 334, 668
982 : 1, 2, 491, 982
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
982 : 1, 2, 491, 982
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,668,982,888,982, is 2.
Now, the common factors can be found like this.
388:2x 2x 97
668:2x 2x 167
982:2x 491
888:2x 2x 2x 3x 37
982:2x 491
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 2x 2x 491 = 15712
Therefore, the value for common factors is 15712.
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 = 221944368235008/(2x15712)
LCM = 221944368235008/31424
LCM = 7062893592
Thus, we can understand that the LCM of 388,668,982,888,982 is 7062893592.
