Given numbers are 2405,9905

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

The LCM of 2405,9905 is 4764305.

Find LCM of 2405,9905 with Prime Factorization

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

5 x 481 x 1981 = 4764305

Therefore, the lowest common multiple of 2405,9905 is 4764305.

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.

2405 x 9905 = 23821525

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.

2405 : 1, 5, 13, 37, 65, 185, 481, 2405

9905 : 1, 5, 7, 35, 283, 1415, 1981, 9905

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2405,9905, is 5.

Now, the common factors can be found like this.

2405:5x 13x 37

9905:5x 7x 283

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

= 1

Therefore, the value for common factors is 1.

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 = 23821525/(5x1)

LCM = 23821525/5

LCM = 4764305

Thus, we can understand that the LCM of 2405,9905 is 4764305.

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

• LCM of 1422, 3001
• LCM of 8371, 3186
