Given numbers are 993,388,817,856

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

The LCM of 993,388,817,856 is 67362283992.

Find LCM of 993,388,817,856 with Prime Factorization

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

2 x 2 x 993 x 97 x 817 x 214 = 67362283992

Therefore, the lowest common multiple of 993,388,817,856 is 67362283992.

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.

993 x 388 x 817 x 856 = 269449135968

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.

993 : 1, 3, 331, 993

388 : 1, 2, 4, 97, 194, 388

817 : 1, 19, 43, 817

856 : 1, 2, 4, 8, 107, 214, 428, 856

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,388,817,856, is 1.

Now, the common factors can be found like this.

993:3x 331

388:2x 2x 97

817:19x 43

856:2x 2x 2x 107

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 = 269449135968/(1x4)

LCM = 269449135968/4

LCM = 67362283992

Thus, we can understand that the LCM of 993,388,817,856 is 67362283992.
