Given numbers are 331,844,440,400,840

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

The LCM of 331,844,440,400,840 is 6453308400.

Find LCM of 331,844,440,400,840 with Prime Factorization

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

2 x 2 x 2 x 5 x 331 x 211 x 11 x 10 x 21 = 6453308400

Therefore, the lowest common multiple of 331,844,440,400,840 is 6453308400.

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.

331 x 844 x 440 x 400 x 840 = 41301173760000

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.

331 : 1, 331

844 : 1, 2, 4, 211, 422, 844

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

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 331,844,440,400,840, is 1.

Now, the common factors can be found like this.

331:331

844:2x 2x 211

440:2x 2x 2x 5x 11

400:2x 2x 2x 2x 5x 5

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 2x 2x 2x 2x 2x 2x 2x 5x 5 = 6400

Therefore, the value for common factors is 6400.

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 = 41301173760000/(1x6400)

LCM = 41301173760000/6400

LCM = 6453308400

Thus, we can understand that the LCM of 331,844,440,400,840 is 6453308400.
