Given numbers are 568,698,345,921

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

The LCM of 568,698,345,921 is 20995742280.

Find LCM of 568,698,345,921 with Prime Factorization

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

2 x 3 x 284 x 349 x 115 x 307 = 20995742280

Therefore, the lowest common multiple of 568,698,345,921 is 20995742280.

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 698 x 345 x 921 = 125974453680

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

698 : 1, 2, 349, 698

345 : 1, 3, 5, 15, 23, 69, 115, 345

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 568,698,345,921, is 1.

Now, the common factors can be found like this.

568:2x 2x 2x 71

698:2x 349

345:3x 5x 23

921:3x 307

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 = 125974453680/(1x6)

LCM = 125974453680/6

LCM = 20995742280

Thus, we can understand that the LCM of 568,698,345,921 is 20995742280.
