Given numbers are 810,461,221,280

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

The LCM of 810,461,221,280 is 2310661080.

Find LCM of 810,461,221,280 with Prime Factorization

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

2 x 5 x 81 x 461 x 221 x 28 = 2310661080

Therefore, the lowest common multiple of 810,461,221,280 is 2310661080.

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 461 x 221 x 280 = 23106610800

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

461 : 1, 461

221 : 1, 13, 17, 221

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,461,221,280, is 1.

Now, the common factors can be found like this.

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

461:461

221:13x 17

280:2x 2x 2x 5x 7

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 23106610800/(1x10)

LCM = 23106610800/10

LCM = 2310661080

Thus, we can understand that the LCM of 810,461,221,280 is 2310661080.
