Given numbers are 5721,1809

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

The LCM of 5721,1809 is 3449763.

Find LCM of 5721,1809 with Prime Factorization

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

3 x 1907 x 603 = 3449763

Therefore, the lowest common multiple of 5721,1809 is 3449763.

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.

5721 x 1809 = 10349289

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.

5721 : 1, 3, 1907, 5721

1809 : 1, 3, 9, 27, 67, 201, 603, 1809

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 5721,1809, is 3.

Now, the common factors can be found like this.

5721:3x 1907

1809:3x 3x 3x 67

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 = 10349289/(3x1)

LCM = 10349289/3

LCM = 3449763

Thus, we can understand that the LCM of 5721,1809 is 3449763.

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

• LCM of 9632, 9262
• LCM of 1818, 2068
