Given numbers are 421,411,321,411

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

The LCM of 421,411,321,411 is 18514317.

Find LCM of 421,411,321,411 with Prime Factorization

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

3 x 137 x 421 x 1 x 107 x 1 = 18514317

Therefore, the lowest common multiple of 421,411,321,411 is 18514317.

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.

421 x 411 x 321 x 411 = 22828152861

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.

421 : 1, 421

411 : 1, 3, 137, 411

321 : 1, 3, 107, 321

411 : 1, 3, 137, 411

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,411,321,411, is 1.

Now, the common factors can be found like this.

421:421

411:3x 137

321:3x 107

411:3x 137

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

3x 3x 137 = 1233

Therefore, the value for common factors is 1233.

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 = 22828152861/(1x1233)

LCM = 22828152861/1233

LCM = 18514317

Thus, we can understand that the LCM of 421,411,321,411 is 18514317.
