Given numbers are 4905,4989

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

The LCM of 4905,4989 is 8157015.

Find LCM of 4905,4989 with Prime Factorization

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

3 x 1635 x 1663 = 8157015

Therefore, the lowest common multiple of 4905,4989 is 8157015.

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.

4905 x 4989 = 24471045

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.

4905 : 1, 3, 5, 9, 15, 45, 109, 327, 545, 981, 1635, 4905

4989 : 1, 3, 1663, 4989

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4905,4989, is 3.

Now, the common factors can be found like this.

4905:3x 3x 5x 109

4989:3x 1663

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 = 24471045/(3x1)

LCM = 24471045/3

LCM = 8157015

Thus, we can understand that the LCM of 4905,4989 is 8157015.

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

• LCM of 3902, 8197
• LCM of 3155, 5260
