Given numbers are 999,637,489,481
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 999,637,489,481 is 103727169.
Find LCM of 999,637,489,481 with Prime Factorization
| 3 | 999, 637, 489, 481 |
| 13 | 333, 637, 163, 481 |
| 37 | 333, 49, 163, 37 |
| 9, 49, 163, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 37 x 9 x 49 x 163 x 1 = 103727169
Therefore, the lowest common multiple of 999,637,489,481 is 103727169.
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.
999 x 637 x 489 x 481 = 149678304867
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.
999 : 1, 3, 9, 27, 37, 111, 333, 999
637 : 1, 7, 13, 49, 91, 637
489 : 1, 3, 163, 489
481 : 1, 13, 37, 481
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 999,637,489,481, is 1.
Now, the common factors can be found like this.
999:3x 3x 3x 37
637:7x 7x 13
489:3x 163
481:13x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 37 = 1443
Therefore, the value for common factors is 1443.
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 = 149678304867/(1x1443)
LCM = 149678304867/1443
LCM = 103727169
Thus, we can understand that the LCM of 999,637,489,481 is 103727169.
