Given numbers are 821,666,429,537

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

The LCM of 821,666,429,537 is 13996081242.

Find LCM of 821,666,429,537 with Prime Factorization

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

3 x 821 x 222 x 143 x 179 = 13996081242

Therefore, the lowest common multiple of 821,666,429,537 is 13996081242.

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 666 x 429 x 537 = 125964731178

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

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

429 : 1, 3, 11, 13, 33, 39, 143, 429

537 : 1, 3, 179, 537

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,666,429,537, is 1.

Now, the common factors can be found like this.

821:821

666:2x 3x 3x 37

429:3x 11x 13

537:3x 179

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 125964731178/(1x9)

LCM = 125964731178/9

LCM = 13996081242

Thus, we can understand that the LCM of 821,666,429,537 is 13996081242.
