Given numbers are 821,540,163,422

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

The LCM of 821,540,163,422 is 15247792620.

Find LCM of 821,540,163,422 with Prime Factorization

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

2 x 821 x 270 x 163 x 211 = 15247792620

Therefore, the lowest common multiple of 821,540,163,422 is 15247792620.

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.

821 x 540 x 163 x 422 = 30495585240

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.

821 : 1, 821

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

163 : 1, 163

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,540,163,422, is 1.

Now, the common factors can be found like this.

821:821

540:2x 2x 3x 3x 3x 5

163:163

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.

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 = 30495585240/(1x2)

LCM = 30495585240/2

LCM = 15247792620

Thus, we can understand that the LCM of 821,540,163,422 is 15247792620.
