Given numbers are 497,451,803,990

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

The LCM of 497,451,803,990 is 1472645790.

Find LCM of 497,451,803,990 with Prime Factorization

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

11 x 497 x 41 x 73 x 90 = 1472645790

Therefore, the lowest common multiple of 497,451,803,990 is 1472645790.

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.

497 x 451 x 803 x 990 = 178190140590

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.

497 : 1, 7, 71, 497

451 : 1, 11, 41, 451

803 : 1, 11, 73, 803

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 497,451,803,990, is 1.

Now, the common factors can be found like this.

497:7x 71

451:11x 41

803:11x 73

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.

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 178190140590/(1x121)

LCM = 178190140590/121

LCM = 1472645790

Thus, we can understand that the LCM of 497,451,803,990 is 1472645790.
