Given numbers are 3991,8021

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

The LCM of 3991,8021 is 2462447.

Find LCM of 3991,8021 with Prime Factorization

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

13 x 307 x 617 = 2462447

Therefore, the lowest common multiple of 3991,8021 is 2462447.

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.

3991 x 8021 = 32011811

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.

3991 : 1, 13, 307, 3991

8021 : 1, 13, 617, 8021

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3991,8021, is 13.

Now, the common factors can be found like this.

3991:13x 307

8021:13x 617

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 = 32011811/(13x1)

LCM = 32011811/13

LCM = 2462447

Thus, we can understand that the LCM of 3991,8021 is 2462447.
