Given numbers are 400,890,215,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,890,215,731 is 26023600.
Find LCM of 400,890,215,731 with Prime Factorization
| 2 | 400, 890, 215, 731 |
| 5 | 200, 445, 215, 731 |
| 43 | 40, 89, 43, 731 |
| 40, 89, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 43 x 40 x 89 x 1 x 17 = 26023600
Therefore, the lowest common multiple of 400,890,215,731 is 26023600.
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 890 x 215 x 731 = 55950740000
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
890 : 1, 2, 5, 10, 89, 178, 445, 890
215 : 1, 5, 43, 215
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,890,215,731, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
890:2x 5x 89
215:5x 43
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 43 = 2150
Therefore, the value for common factors is 2150.
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 = 55950740000/(1x2150)
LCM = 55950740000/2150
LCM = 26023600
Thus, we can understand that the LCM of 400,890,215,731 is 26023600.
