Given numbers are 421,923,439,842

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

The LCM of 421,923,439,842 is 341175874.

Find LCM of 421,923,439,842 with Prime Factorization

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

421 x 1 x 923 x 439 x 2 = 341175874

Therefore, the lowest common multiple of 421,923,439,842 is 341175874.

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.

421 x 923 x 439 x 842 = 143635042954

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.

421 : 1, 421

923 : 1, 13, 71, 923

439 : 1, 439

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,923,439,842, is 1.

Now, the common factors can be found like this.

421:421

923:13x 71

439:439

842:2x 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 = 143635042954/(1x421)

LCM = 143635042954/421

LCM = 341175874

Thus, we can understand that the LCM of 421,923,439,842 is 341175874.
