Given numbers are 485,284,642,621

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

The LCM of 485,284,642,621 is 9152409780.

Find LCM of 485,284,642,621 with Prime Factorization

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

2 x 3 x 485 x 142 x 107 x 207 = 9152409780

Therefore, the lowest common multiple of 485,284,642,621 is 9152409780.

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.

485 x 284 x 642 x 621 = 54914458680

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.

485 : 1, 5, 97, 485

284 : 1, 2, 4, 71, 142, 284

642 : 1, 2, 3, 6, 107, 214, 321, 642

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 485,284,642,621, is 1.

Now, the common factors can be found like this.

485:5x 97

284:2x 2x 71

642:2x 3x 107

621:3x 3x 3x 23

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 54914458680/(1x6)

LCM = 54914458680/6

LCM = 9152409780

Thus, we can understand that the LCM of 485,284,642,621 is 9152409780.
