Given numbers are 27,513,921

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

The LCM of 27,513,921 is 157491.

Find LCM of 27,513,921 with Prime Factorization

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

3 x 3 x 3 x 1 x 19 x 307 = 157491

Therefore, the lowest common multiple of 27,513,921 is 157491.

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.

27 x 513 x 921 = 12756771

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.

27 : 1, 3, 9, 27

513 : 1, 3, 9, 19, 27, 57, 171, 513

921 : 1, 3, 307, 921

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 27,513,921, is 3.

Now, the common factors can be found like this.

27:3x 3x 3

513:3x 3x 3x 19

921:3x 307

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 3 = 27

Therefore, the value for common factors is 27.

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 = 12756771/(3x27)

LCM = 12756771/81

LCM = 157491

Thus, we can understand that the LCM of 27,513,921 is 157491.

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

• LCM of 55, 129, 758
• LCM of 63, 819, 577
