Given numbers are 843,160,990,654,397
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,160,990,654,397 is 192609853920.
Find LCM of 843,160,990,654,397 with Prime Factorization
| 2 | 843, 160, 990, 654, 397 |
| 3 | 843, 80, 495, 327, 397 |
| 5 | 281, 80, 165, 109, 397 |
| 281, 16, 33, 109, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 281 x 16 x 33 x 109 x 397 = 192609853920
Therefore, the lowest common multiple of 843,160,990,654,397 is 192609853920.
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.
843 x 160 x 990 x 654 x 397 = 34669773705600
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.
843 : 1, 3, 281, 843
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
654 : 1, 2, 3, 6, 109, 218, 327, 654
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,160,990,654,397, is 1.
Now, the common factors can be found like this.
843:3x 281
160:2x 2x 2x 2x 2x 5
990:2x 3x 3x 5x 11
654:2x 3x 109
397:397
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 34669773705600/(1x180)
LCM = 34669773705600/180
LCM = 192609853920
Thus, we can understand that the LCM of 843,160,990,654,397 is 192609853920.
