Given numbers are 442,810,401

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

The LCM of 442,810,401 is 71783010.

Find LCM of 442,810,401 with Prime Factorization

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

2 x 221 x 405 x 401 = 71783010

Therefore, the lowest common multiple of 442,810,401 is 71783010.

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.

442 x 810 x 401 = 143566020

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

401 : 1, 401

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,810,401, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

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

401:401

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

2 = 2

Therefore, the value for common factors is 2.

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 = 143566020/(1x2)

LCM = 143566020/2

LCM = 71783010

Thus, we can understand that the LCM of 442,810,401 is 71783010.
