Given numbers are 810,280,653,485,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,280,653,485,557 is 800171651160.
Find LCM of 810,280,653,485,557 with Prime Factorization
| 2 | 810, 280, 653, 485, 557 |
| 5 | 405, 140, 653, 485, 557 |
| 81, 28, 653, 97, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 81 x 28 x 653 x 97 x 557 = 800171651160
Therefore, the lowest common multiple of 810,280,653,485,557 is 800171651160.
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.
810 x 280 x 653 x 485 x 557 = 40008582558000
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
653 : 1, 653
485 : 1, 5, 97, 485
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,280,653,485,557, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
280:2x 2x 2x 5x 7
653:653
485:5x 97
557:557
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 5 = 50
Therefore, the value for common factors is 50.
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 = 40008582558000/(1x50)
LCM = 40008582558000/50
LCM = 800171651160
Thus, we can understand that the LCM of 810,280,653,485,557 is 800171651160.
