Given numbers are 838,344,646,646,180
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,344,646,646,180 is 2095016760.
Find LCM of 838,344,646,646,180 with Prime Factorization
| 2 | 838, 344, 646, 646, 180 |
| 2 | 419, 172, 323, 323, 90 |
| 17 | 419, 86, 323, 323, 45 |
| 19 | 419, 86, 19, 19, 45 |
| 419, 86, 1, 1, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 19 x 419 x 86 x 1 x 1 x 45 = 2095016760
Therefore, the lowest common multiple of 838,344,646,646,180 is 2095016760.
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.
838 x 344 x 646 x 646 x 180 = 21654093231360
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.
838 : 1, 2, 419, 838
344 : 1, 2, 4, 8, 43, 86, 172, 344
646 : 1, 2, 17, 19, 34, 38, 323, 646
646 : 1, 2, 17, 19, 34, 38, 323, 646
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,344,646,646,180, is 2.
Now, the common factors can be found like this.
838:2x 419
344:2x 2x 2x 43
646:2x 17x 19
646:2x 17x 19
180:2x 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.
2x 2x 2x 2x 17x 19 = 5168
Therefore, the value for common factors is 5168.
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 = 21654093231360/(2x5168)
LCM = 21654093231360/10336
LCM = 2095016760
Thus, we can understand that the LCM of 838,344,646,646,180 is 2095016760.
