Given numbers are 642,214,993,863

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

The LCM of 642,214,993,863 is 183389226.

Find LCM of 642,214,993,863 with Prime Factorization

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

2 x 3 x 107 x 1 x 1 x 331 x 863 = 183389226

Therefore, the lowest common multiple of 642,214,993,863 is 183389226.

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.

642 x 214 x 993 x 863 = 117735883092

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.

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

214 : 1, 2, 107, 214

993 : 1, 3, 331, 993

863 : 1, 863

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,214,993,863, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

214:2x 107

993:3x 331

863:863

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

2x 3x 107 = 642

Therefore, the value for common factors is 642.

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 = 117735883092/(1x642)

LCM = 117735883092/642

LCM = 183389226

Thus, we can understand that the LCM of 642,214,993,863 is 183389226.
