Given numbers are 207,19,621

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

The LCM of 207,19,621 is 11799.

Find LCM of 207,19,621 with Prime Factorization

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

3 x 3 x 23 x 1 x 19 x 3 = 11799

Therefore, the lowest common multiple of 207,19,621 is 11799.

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.

207 x 19 x 621 = 2442393

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.

207 : 1, 3, 9, 23, 69, 207

19 : 1, 19

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,19,621, is 1.

Now, the common factors can be found like this.

207:3x 3x 23

19:19

621:3x 3x 3x 23

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 23 = 207

Therefore, the value for common factors is 207.

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 = 2442393/(1x207)

LCM = 2442393/207

LCM = 11799

Thus, we can understand that the LCM of 207,19,621 is 11799.

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

• LCM of 634, 97, 467
• LCM of 703, 75, 475
