Given numbers are 568,956,691,821

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

The LCM of 568,956,691,821 is 77013602872.

Find LCM of 568,956,691,821 with Prime Factorization

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

2 x 2 x 142 x 239 x 691 x 821 = 77013602872

Therefore, the lowest common multiple of 568,956,691,821 is 77013602872.

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 956 x 691 x 821 = 308054411488

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

956 : 1, 2, 4, 239, 478, 956

691 : 1, 691

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 568,956,691,821, is 1.

Now, the common factors can be found like this.

568:2x 2x 2x 71

956:2x 2x 239

691:691

821:821

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 308054411488/(1x4)

LCM = 308054411488/4

LCM = 77013602872

Thus, we can understand that the LCM of 568,956,691,821 is 77013602872.
