Given numbers are 642,842,464,841

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

The LCM of 642,842,464,841 is 1818457296.

Find LCM of 642,842,464,841 with Prime Factorization

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

2 x 29 x 321 x 421 x 8 x 29 = 1818457296

Therefore, the lowest common multiple of 642,842,464,841 is 1818457296.

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 842 x 464 x 841 = 210941046336

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

842 : 1, 2, 421, 842

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

841 : 1, 29, 841

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,842,464,841, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

842:2x 421

464:2x 2x 2x 2x 29

841:29x 29

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 29 = 116

Therefore, the value for common factors is 116.

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 = 210941046336/(1x116)

LCM = 210941046336/116

LCM = 1818457296

Thus, we can understand that the LCM of 642,842,464,841 is 1818457296.
