Given numbers are 636,873,556,21

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

The LCM of 636,873,556,21 is 180078948.

Find LCM of 636,873,556,21 with Prime Factorization

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

2 x 2 x 3 x 53 x 291 x 139 x 7 = 180078948

Therefore, the lowest common multiple of 636,873,556,21 is 180078948.

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.

636 x 873 x 556 x 21 = 6482842128

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.

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

873 : 1, 3, 9, 97, 291, 873

556 : 1, 2, 4, 139, 278, 556

21 : 1, 3, 7, 21

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,873,556,21, is 1.

Now, the common factors can be found like this.

636:2x 2x 3x 53

873:3x 3x 97

556:2x 2x 139

21:3x 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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 6482842128/(1x36)

LCM = 6482842128/36

LCM = 180078948

Thus, we can understand that the LCM of 636,873,556,21 is 180078948.
