Given numbers are 489,374,660,159
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,374,660,159 is 96929580.
Find LCM of 489,374,660,159 with Prime Factorization
| 2 | 489, 374, 660, 159 |
| 3 | 489, 187, 330, 159 |
| 11 | 163, 187, 110, 53 |
| 163, 17, 10, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 163 x 17 x 10 x 53 = 96929580
Therefore, the lowest common multiple of 489,374,660,159 is 96929580.
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 374 x 660 x 159 = 19192056840
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
374 : 1, 2, 11, 17, 22, 34, 187, 374
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
159 : 1, 3, 53, 159
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,374,660,159, is 1.
Now, the common factors can be found like this.
489:3x 163
374:2x 11x 17
660:2x 2x 3x 5x 11
159:3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 19192056840/(1x198)
LCM = 19192056840/198
LCM = 96929580
Thus, we can understand that the LCM of 489,374,660,159 is 96929580.
