Given numbers are 399,810,525,409,840

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

The LCM of 399,810,525,409,840 is 881231400.

Find LCM of 399,810,525,409,840 with Prime Factorization

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

2 x 3 x 5 x 7 x 19 x 27 x 5 x 409 x 4 = 881231400

Therefore, the lowest common multiple of 399,810,525,409,840 is 881231400.

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.

399 x 810 x 525 x 409 x 840 = 58293457110000

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

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

525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525

409 : 1, 409

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,810,525,409,840, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

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

525:3x 5x 5x 7

409:409

840:2x 2x 2x 3x 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 3x 3x 3x 5x 5x 7x 7 = 66150

Therefore, the value for common factors is 66150.

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 = 58293457110000/(1x66150)

LCM = 58293457110000/66150

LCM = 881231400

Thus, we can understand that the LCM of 399,810,525,409,840 is 881231400.
