Given numbers are 489,319,660,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,319,660,697 is 2174514540.
Find LCM of 489,319,660,697 with Prime Factorization
| 3 | 489, 319, 660, 697 |
| 11 | 163, 319, 220, 697 |
| 163, 29, 20, 697 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 163 x 29 x 20 x 697 = 2174514540
Therefore, the lowest common multiple of 489,319,660,697 is 2174514540.
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 319 x 660 x 697 = 71758979820
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
319 : 1, 11, 29, 319
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
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,319,660,697, is 1.
Now, the common factors can be found like this.
489:3x 163
319:11x 29
660:2x 2x 3x 5x 11
697:17x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 71758979820/(1x33)
LCM = 71758979820/33
LCM = 2174514540
Thus, we can understand that the LCM of 489,319,660,697 is 2174514540.
