Given numbers are 6403,8455

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

The LCM of 6403,8455 is 2849335.

Find LCM of 6403,8455 with Prime Factorization

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

19 x 337 x 445 = 2849335

Therefore, the lowest common multiple of 6403,8455 is 2849335.

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.

6403 x 8455 = 54137365

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.

6403 : 1, 19, 337, 6403

8455 : 1, 5, 19, 89, 95, 445, 1691, 8455

19 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6403,8455, is 19.

Now, the common factors can be found like this.

6403:19x 337

8455:5x 19x 89

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 = 54137365/(19x1)

LCM = 54137365/19

LCM = 2849335

Thus, we can understand that the LCM of 6403,8455 is 2849335.
