Given numbers are 130,800,131,998

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

The LCM of 130,800,131,998 is 679837600.

Find LCM of 130,800,131,998 with Prime Factorization

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

2 x 5 x 13 x 80 x 131 x 499 = 679837600

Therefore, the lowest common multiple of 130,800,131,998 is 679837600.

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.

130 x 800 x 131 x 998 = 13596752000

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.

130 : 1, 2, 5, 10, 13, 26, 65, 130

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

131 : 1, 131

998 : 1, 2, 499, 998

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,800,131,998, is 1.

Now, the common factors can be found like this.

130:2x 5x 13

800:2x 2x 2x 2x 2x 5x 5

131:131

998:2x 499

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 13596752000/(1x20)

LCM = 13596752000/20

LCM = 679837600

Thus, we can understand that the LCM of 130,800,131,998 is 679837600.

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