Given numbers are 578,810,687,200,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,810,687,200,805 is 172613284200.
Find LCM of 578,810,687,200,805 with Prime Factorization
| 2 | 578, 810, 687, 200, 805 |
| 3 | 289, 405, 687, 100, 805 |
| 5 | 289, 135, 229, 100, 805 |
| 289, 27, 229, 20, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 289 x 27 x 229 x 20 x 161 = 172613284200
Therefore, the lowest common multiple of 578,810,687,200,805 is 172613284200.
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.
578 x 810 x 687 x 200 x 805 = 51783985260000
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.
578 : 1, 2, 17, 34, 289, 578
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
687 : 1, 3, 229, 687
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,810,687,200,805, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
810:2x 3x 3x 3x 3x 5
687:3x 229
200:2x 2x 2x 5x 5
805:5x 7x 23
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 3x 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 51783985260000/(1x300)
LCM = 51783985260000/300
LCM = 172613284200
Thus, we can understand that the LCM of 578,810,687,200,805 is 172613284200.
