Given numbers are 4638,9021

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

The LCM of 4638,9021 is 13946466.

Find LCM of 4638,9021 with Prime Factorization

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

3 x 1546 x 3007 = 13946466

Therefore, the lowest common multiple of 4638,9021 is 13946466.

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.

4638 x 9021 = 41839398

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.

4638 : 1, 2, 3, 6, 773, 1546, 2319, 4638

9021 : 1, 3, 31, 93, 97, 291, 3007, 9021

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4638,9021, is 3.

Now, the common factors can be found like this.

4638:2x 3x 773

9021:3x 31x 97

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 = 41839398/(3x1)

LCM = 41839398/3

LCM = 13946466

Thus, we can understand that the LCM of 4638,9021 is 13946466.

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

• LCM of 8988, 6601
• LCM of 8302, 2831
