Given numbers are 649,183,808,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,183,808,489 is 15642088968.
Find LCM of 649,183,808,489 with Prime Factorization
| 3 | 649, 183, 808, 489 |
| 649, 61, 808, 163 |
Multiply the prime numbers at the bottom and the left side.
3 x 649 x 61 x 808 x 163 = 15642088968
Therefore, the lowest common multiple of 649,183,808,489 is 15642088968.
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.
649 x 183 x 808 x 489 = 46926266904
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.
649 : 1, 11, 59, 649
183 : 1, 3, 61, 183
808 : 1, 2, 4, 8, 101, 202, 404, 808
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,183,808,489, is 1.
Now, the common factors can be found like this.
649:11x 59
183:3x 61
808:2x 2x 2x 101
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 46926266904/(1x3)
LCM = 46926266904/3
LCM = 15642088968
Thus, we can understand that the LCM of 649,183,808,489 is 15642088968.
