Given numbers are 485,388,720,850
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 485,388,720,850 is 5936400.
Find LCM of 485,388,720,850 with Prime Factorization
| 2 | 485, 388, 720, 850 |
| 2 | 485, 194, 360, 425 |
| 5 | 485, 97, 180, 425 |
| 97 | 97, 97, 36, 85 |
| 1, 1, 36, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 97 x 1 x 1 x 36 x 85 = 5936400
Therefore, the lowest common multiple of 485,388,720,850 is 5936400.
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.
485 x 388 x 720 x 850 = 115166160000
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.
485 : 1, 5, 97, 485
388 : 1, 2, 4, 97, 194, 388
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 485,388,720,850, is 1.
Now, the common factors can be found like this.
485:5x 97
388:2x 2x 97
720:2x 2x 2x 2x 3x 3x 5
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 5x 5x 97 = 19400
Therefore, the value for common factors is 19400.
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 = 115166160000/(1x19400)
LCM = 115166160000/19400
LCM = 5936400
Thus, we can understand that the LCM of 485,388,720,850 is 5936400.
