Given numbers are 489,793,681,621

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

The LCM of 489,793,681,621 is 18221253453.

Find LCM of 489,793,681,621 with Prime Factorization

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

3 x 163 x 793 x 227 x 207 = 18221253453

Therefore, the lowest common multiple of 489,793,681,621 is 18221253453.

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.

489 x 793 x 681 x 621 = 163991281077

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.

489 : 1, 3, 163, 489

793 : 1, 13, 61, 793

681 : 1, 3, 227, 681

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 489,793,681,621, is 1.

Now, the common factors can be found like this.

489:3x 163

793:13x 61

681:3x 227

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.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 163991281077/(1x9)

LCM = 163991281077/9

LCM = 18221253453

Thus, we can understand that the LCM of 489,793,681,621 is 18221253453.
