Given numbers are 6391,5401

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

The LCM of 6391,5401 is 3137981.

Find LCM of 6391,5401 with Prime Factorization

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

11 x 581 x 491 = 3137981

Therefore, the lowest common multiple of 6391,5401 is 3137981.

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.

6391 x 5401 = 34517791

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.

6391 : 1, 7, 11, 77, 83, 581, 913, 6391

5401 : 1, 11, 491, 5401

11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6391,5401, is 11.

Now, the common factors can be found like this.

6391:7x 11x 83

5401:11x 491

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 = 34517791/(11x1)

LCM = 34517791/11

LCM = 3137981

Thus, we can understand that the LCM of 6391,5401 is 3137981.

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

• LCM of 3314, 4508
