Given numbers are 400,731,382,374,382
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,731,382,374,382 is 614332400.
Find LCM of 400,731,382,374,382 with Prime Factorization
| 2 | 400, 731, 382, 374, 382 |
| 17 | 200, 731, 191, 187, 191 |
| 191 | 200, 43, 191, 11, 191 |
| 200, 43, 1, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 191 x 200 x 43 x 1 x 11 x 1 = 614332400
Therefore, the lowest common multiple of 400,731,382,374,382 is 614332400.
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.
400 x 731 x 382 x 374 x 382 = 15957898422400
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
731 : 1, 17, 43, 731
382 : 1, 2, 191, 382
374 : 1, 2, 11, 17, 22, 34, 187, 374
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,731,382,374,382, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
731:17x 43
382:2x 191
374:2x 11x 17
382:2x 191
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 17x 191 = 25976
Therefore, the value for common factors is 25976.
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 = 15957898422400/(1x25976)
LCM = 15957898422400/25976
LCM = 614332400
Thus, we can understand that the LCM of 400,731,382,374,382 is 614332400.
