Given numbers are 405,401,401

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

The LCM of 405,401,401 is 162405.

Find LCM of 405,401,401 with Prime Factorization

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

401 x 405 x 1 x 1 = 162405

Therefore, the lowest common multiple of 405,401,401 is 162405.

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.

405 x 401 x 401 = 65124405

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.

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

401 : 1, 401

401 : 1, 401

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,401,401, is 1.

Now, the common factors can be found like this.

405:3x 3x 3x 3x 5

401:401

401:401

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

401 = 401

Therefore, the value for common factors is 401.

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 = 65124405/(1x401)

LCM = 65124405/401

LCM = 162405

Thus, we can understand that the LCM of 405,401,401 is 162405.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 485, 464, 263
• LCM of 515, 921, 395
