Given numbers are 803,281,990

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

The LCM of 803,281,990 is 20307870.

Find LCM of 803,281,990 with Prime Factorization

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

11 x 73 x 281 x 90 = 20307870

Therefore, the lowest common multiple of 803,281,990 is 20307870.

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.

803 x 281 x 990 = 223386570

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.

803 : 1, 11, 73, 803

281 : 1, 281

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,281,990, is 1.

Now, the common factors can be found like this.

803:11x 73

281:281

990:2x 3x 3x 5x 11

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

11 = 11

Therefore, the value for common factors is 11.

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 = 223386570/(1x11)

LCM = 223386570/11

LCM = 20307870

Thus, we can understand that the LCM of 803,281,990 is 20307870.
