Given numbers are 816,440,880,422

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

The LCM of 816,440,880,422 is 9469680.

Find LCM of 816,440,880,422 with Prime Factorization

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

2 x 2 x 2 x 2 x 5 x 11 x 51 x 1 x 1 x 211 = 9469680

Therefore, the lowest common multiple of 816,440,880,422 is 9469680.

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.

816 x 440 x 880 x 422 = 133333094400

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.

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

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

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

422 : 1, 2, 211, 422

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,440,880,422, is 2.

Now, the common factors can be found like this.

816:2x 2x 2x 2x 3x 17

440:2x 2x 2x 5x 11

880:2x 2x 2x 2x 5x 11

422:2x 211

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 5x 11 = 7040

Therefore, the value for common factors is 7040.

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 = 133333094400/(2x7040)

LCM = 133333094400/14080

LCM = 9469680

Thus, we can understand that the LCM of 816,440,880,422 is 9469680.
