Given numbers are 6639,5865

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

The LCM of 6639,5865 is 12979245.

Find LCM of 6639,5865 with Prime Factorization

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

3 x 2213 x 1955 = 12979245

Therefore, the lowest common multiple of 6639,5865 is 12979245.

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.

6639 x 5865 = 38937735

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.

6639 : 1, 3, 2213, 6639

5865 : 1, 3, 5, 15, 17, 23, 51, 69, 85, 115, 255, 345, 391, 1173, 1955, 5865

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6639,5865, is 3.

Now, the common factors can be found like this.

6639:3x 2213

5865:3x 5x 17x 23

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 = 38937735/(3x1)

LCM = 38937735/3

LCM = 12979245

Thus, we can understand that the LCM of 6639,5865 is 12979245.

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

• LCM of 4469, 1389
• LCM of 5305, 1661
