Given numbers are 642,214,803,830,674

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

The LCM of 642,214,803,830,674 is 72098888730.

Find LCM of 642,214,803,830,674 with Prime Factorization

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

2 x 107 x 3 x 1 x 803 x 415 x 337 = 72098888730

Therefore, the lowest common multiple of 642,214,803,830,674 is 72098888730.

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 803 x 830 x 674 = 61716648752880

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

803 : 1, 11, 73, 803

830 : 1, 2, 5, 10, 83, 166, 415, 830

674 : 1, 2, 337, 674

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,214,803,830,674, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

214:2x 107

803:11x 73

830:2x 5x 83

674:2x 337

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 107 = 856

Therefore, the value for common factors is 856.

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 = 61716648752880/(1x856)

LCM = 61716648752880/856

LCM = 72098888730

Thus, we can understand that the LCM of 642,214,803,830,674 is 72098888730.
