Given numbers are 380,810,731,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,810,731,442 is 292502340.
Find LCM of 380,810,731,442 with Prime Factorization
| 2 | 380, 810, 731, 442 |
| 5 | 190, 405, 731, 221 |
| 17 | 38, 81, 731, 221 |
| 38, 81, 43, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 38 x 81 x 43 x 13 = 292502340
Therefore, the lowest common multiple of 380,810,731,442 is 292502340.
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.
380 x 810 x 731 x 442 = 99450795600
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
731 : 1, 17, 43, 731
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,810,731,442, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
810:2x 3x 3x 3x 3x 5
731:17x 43
442:2x 13x 17
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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 99450795600/(1x340)
LCM = 99450795600/340
LCM = 292502340
Thus, we can understand that the LCM of 380,810,731,442 is 292502340.
