Given numbers are 489,349,687,147
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,349,687,147 is 1914987081.
Find LCM of 489,349,687,147 with Prime Factorization
| 3 | 489, 349, 687, 147 |
| 163, 349, 229, 49 |
Multiply the prime numbers at the bottom and the left side.
3 x 163 x 349 x 229 x 49 = 1914987081
Therefore, the lowest common multiple of 489,349,687,147 is 1914987081.
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.
489 x 349 x 687 x 147 = 17234883729
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.
489 : 1, 3, 163, 489
349 : 1, 349
687 : 1, 3, 229, 687
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,349,687,147, is 1.
Now, the common factors can be found like this.
489:3x 163
349:349
687:3x 229
147:3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 17234883729/(1x9)
LCM = 17234883729/9
LCM = 1914987081
Thus, we can understand that the LCM of 489,349,687,147 is 1914987081.
