Given numbers are 9985,8020

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

The LCM of 9985,8020 is 16015940.

Find LCM of 9985,8020 with Prime Factorization

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

5 x 1997 x 1604 = 16015940

Therefore, the lowest common multiple of 9985,8020 is 16015940.

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.

9985 x 8020 = 80079700

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.

9985 : 1, 5, 1997, 9985

8020 : 1, 2, 4, 5, 10, 20, 401, 802, 1604, 2005, 4010, 8020

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 9985,8020, is 5.

Now, the common factors can be found like this.

9985:5x 1997

8020:2x 2x 5x 401

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 = 80079700/(5x1)

LCM = 80079700/5

LCM = 16015940

Thus, we can understand that the LCM of 9985,8020 is 16015940.

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

• LCM of 2261, 3078
• LCM of 8527, 1880
