Given numbers are 568,209,451,861

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

The LCM of 568,209,451,861 is 102211032.

Find LCM of 568,209,451,861 with Prime Factorization

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

11 x 41 x 568 x 19 x 1 x 21 = 102211032

Therefore, the lowest common multiple of 568,209,451,861 is 102211032.

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.

568 x 209 x 451 x 861 = 46097175432

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.

568 : 1, 2, 4, 8, 71, 142, 284, 568

209 : 1, 11, 19, 209

451 : 1, 11, 41, 451

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 568,209,451,861, is 1.

Now, the common factors can be found like this.

568:2x 2x 2x 71

209:11x 19

451:11x 41

861:3x 7x 41

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

11x 41 = 451

Therefore, the value for common factors is 451.

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 = 46097175432/(1x451)

LCM = 46097175432/451

LCM = 102211032

Thus, we can understand that the LCM of 568,209,451,861 is 102211032.
