Given numbers are 920,800,442,850
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,800,442,850 is 4066400.
Find LCM of 920,800,442,850 with Prime Factorization
| 2 | 920, 800, 442, 850 |
| 2 | 460, 400, 221, 425 |
| 2 | 230, 200, 221, 425 |
| 5 | 115, 100, 221, 425 |
| 5 | 23, 20, 221, 85 |
| 17 | 23, 4, 221, 17 |
| 23, 4, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 5 x 17 x 23 x 4 x 13 x 1 = 4066400
Therefore, the lowest common multiple of 920,800,442,850 is 4066400.
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.
920 x 800 x 442 x 850 = 276515200000
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
442 : 1, 2, 13, 17, 26, 34, 221, 442
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,800,442,850, is 2.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
800:2x 2x 2x 2x 2x 5x 5
442:2x 13x 17
850:2x 5x 5x 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 2x 2x 5x 5x 5x 17 = 34000
Therefore, the value for common factors is 34000.
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 = 276515200000/(2x34000)
LCM = 276515200000/68000
LCM = 4066400
Thus, we can understand that the LCM of 920,800,442,850 is 4066400.
