Given numbers are 818,936,642,786,921

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

The LCM of 818,936,642,786,921 is 1647375510456.

Find LCM of 818,936,642,786,921 with Prime Factorization

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

2 x 3 x 409 x 156 x 107 x 131 x 307 = 1647375510456

Therefore, the lowest common multiple of 818,936,642,786,921 is 1647375510456.

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.

818 x 936 x 642 x 786 x 921 = 355833110258496

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.

818 : 1, 2, 409, 818

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

642 : 1, 2, 3, 6, 107, 214, 321, 642

786 : 1, 2, 3, 6, 131, 262, 393, 786

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,936,642,786,921, is 1.

Now, the common factors can be found like this.

818:2x 409

936:2x 2x 2x 3x 3x 13

642:2x 3x 107

786:2x 3x 131

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 2x 2x 3x 3x 3 = 216

Therefore, the value for common factors is 216.

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 = 355833110258496/(1x216)

LCM = 355833110258496/216

LCM = 1647375510456

Thus, we can understand that the LCM of 818,936,642,786,921 is 1647375510456.
