Given numbers are 393,842,381,381

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

The LCM of 393,842,381,381 is 42025062.

Find LCM of 393,842,381,381 with Prime Factorization

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

3 x 127 x 131 x 842 x 1 x 1 = 42025062

Therefore, the lowest common multiple of 393,842,381,381 is 42025062.

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.

393 x 842 x 381 x 381 = 48034645866

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.

393 : 1, 3, 131, 393

842 : 1, 2, 421, 842

381 : 1, 3, 127, 381

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,842,381,381, is 1.

Now, the common factors can be found like this.

393:3x 131

842:2x 421

381:3x 127

381:3x 127

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

3x 3x 127 = 1143

Therefore, the value for common factors is 1143.

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 = 48034645866/(1x1143)

LCM = 48034645866/1143

LCM = 42025062

Thus, we can understand that the LCM of 393,842,381,381 is 42025062.
