Given numbers are 439,539,842,421

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

The LCM of 439,539,842,421 is 199234882.

Find LCM of 439,539,842,421 with Prime Factorization

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

421 x 439 x 539 x 2 x 1 = 199234882

Therefore, the lowest common multiple of 439,539,842,421 is 199234882.

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.

439 x 539 x 842 x 421 = 83877885322

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.

439 : 1, 439

539 : 1, 7, 11, 49, 77, 539

842 : 1, 2, 421, 842

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 439,539,842,421, is 1.

Now, the common factors can be found like this.

439:439

539:7x 7x 11

842:2x 421

421:421

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

421 = 421

Therefore, the value for common factors is 421.

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 = 83877885322/(1x421)

LCM = 83877885322/421

LCM = 199234882

Thus, we can understand that the LCM of 439,539,842,421 is 199234882.
