Given numbers are 259,161,147,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 259,161,147,489 is 20390811.
Find LCM of 259,161,147,489 with Prime Factorization
| 3 | 259, 161, 147, 489 |
| 7 | 259, 161, 49, 163 |
| 37, 23, 7, 163 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 37 x 23 x 7 x 163 = 20390811
Therefore, the lowest common multiple of 259,161,147,489 is 20390811.
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.
259 x 161 x 147 x 489 = 2997449217
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.
259 : 1, 7, 37, 259
161 : 1, 7, 23, 161
147 : 1, 3, 7, 21, 49, 147
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 259,161,147,489, is 1.
Now, the common factors can be found like this.
259:7x 37
161:7x 23
147:3x 7x 7
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.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 2997449217/(1x147)
LCM = 2997449217/147
LCM = 20390811
Thus, we can understand that the LCM of 259,161,147,489 is 20390811.
