Given numbers are 489,817,289,289,360
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,817,289,289,360 is 13855110840.
Find LCM of 489,817,289,289,360 with Prime Factorization
3 | 489, 817, 289, 289, 360 |
17 | 163, 817, 289, 289, 120 |
17 | 163, 817, 17, 17, 120 |
163, 817, 1, 1, 120 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 17 x 163 x 817 x 1 x 1 x 120 = 13855110840
Therefore, the lowest common multiple of 489,817,289,289,360 is 13855110840.
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 817 x 289 x 289 x 360 = 12012381098280
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
817 : 1, 19, 43, 817
289 : 1, 17, 289
289 : 1, 17, 289
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,817,289,289,360, is 1.
Now, the common factors can be found like this.
489:3x 163
817:19x 43
289:17x 17
289:17x 17
360:2x 2x 2x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17x 17 = 867
Therefore, the value for common factors is 867.
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 = 12012381098280/(1x867)
LCM = 12012381098280/867
LCM = 13855110840
Thus, we can understand that the LCM of 489,817,289,289,360 is 13855110840.
