Given numbers are 421,842,944,395

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

The LCM of 421,842,944,395 is 156982480.

Find LCM of 421,842,944,395 with Prime Factorization

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

2 x 421 x 1 x 1 x 472 x 395 = 156982480

Therefore, the lowest common multiple of 421,842,944,395 is 156982480.

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 842 x 944 x 395 = 132179248160

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

842 : 1, 2, 421, 842

944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,842,944,395, is 1.

Now, the common factors can be found like this.

421:421

842:2x 421

944:2x 2x 2x 2x 59

395:5x 79

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

2x 421 = 842

Therefore, the value for common factors is 842.

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 = 132179248160/(1x842)

LCM = 132179248160/842

LCM = 156982480

Thus, we can understand that the LCM of 421,842,944,395 is 156982480.
