Given numbers are 810,840,355,611,497

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 810,840,355,611,497 is 983881080.

Find LCM of 810,840,355,611,497 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 5 x 7 x 71 x 27 x 4 x 1 x 611 x 1 = 983881080

Therefore, the lowest common multiple of 810,840,355,611,497 is 983881080.

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 840 x 355 x 611 x 497 = 73348334514000

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

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

355 : 1, 5, 71, 355

611 : 1, 13, 47, 611

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,840,355,611,497, is 1.

Now, the common factors can be found like this.

810:2x 3x 3x 3x 3x 5

840:2x 2x 2x 3x 5x 7

355:5x 71

611:13x 47

497:7x 71

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 5x 5x 7x 71 = 74550

Therefore, the value for common factors is 74550.

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 = 73348334514000/(1x74550)

LCM = 73348334514000/74550

LCM = 983881080

Thus, we can understand that the LCM of 810,840,355,611,497 is 983881080.
