Given numbers are 341,289,646,396
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 341,289,646,396 is 67407516.
Find LCM of 341,289,646,396 with Prime Factorization
| 2 | 341, 289, 646, 396 |
| 11 | 341, 289, 323, 198 |
| 17 | 31, 289, 323, 18 |
| 31, 17, 19, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 31 x 17 x 19 x 18 = 67407516
Therefore, the lowest common multiple of 341,289,646,396 is 67407516.
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.
341 x 289 x 646 x 396 = 25210410984
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.
341 : 1, 11, 31, 341
289 : 1, 17, 289
646 : 1, 2, 17, 19, 34, 38, 323, 646
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 341,289,646,396, is 1.
Now, the common factors can be found like this.
341:11x 31
289:17x 17
646:2x 17x 19
396:2x 2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 17 = 374
Therefore, the value for common factors is 374.
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 = 25210410984/(1x374)
LCM = 25210410984/374
LCM = 67407516
Thus, we can understand that the LCM of 341,289,646,396 is 67407516.
