Given numbers are 4070,9986

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

The LCM of 4070,9986 is 20321510.

Find LCM of 4070,9986 with Prime Factorization

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

2 x 2035 x 4993 = 20321510

Therefore, the lowest common multiple of 4070,9986 is 20321510.

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.

4070 x 9986 = 40643020

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.

4070 : 1, 2, 5, 10, 11, 22, 37, 55, 74, 110, 185, 370, 407, 814, 2035, 4070

9986 : 1, 2, 4993, 9986

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4070,9986, is 2.

Now, the common factors can be found like this.

4070:2x 5x 11x 37

9986:2x 4993

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 = 40643020/(2x1)

LCM = 40643020/2

LCM = 20321510

Thus, we can understand that the LCM of 4070,9986 is 20321510.

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

• LCM of 7454, 1739
• LCM of 1975, 8704
