Given numbers are 394,403,855,394

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

The LCM of 394,403,855,394 is 135758610.

Find LCM of 394,403,855,394 with Prime Factorization

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

2 x 197 x 1 x 403 x 855 x 1 = 135758610

Therefore, the lowest common multiple of 394,403,855,394 is 135758610.

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.

394 x 403 x 855 x 394 = 53488892340

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.

394 : 1, 2, 197, 394

403 : 1, 13, 31, 403

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,403,855,394, is 1.

Now, the common factors can be found like this.

394:2x 197

403:13x 31

855:3x 3x 5x 19

394:2x 197

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

2x 197 = 394

Therefore, the value for common factors is 394.

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 = 53488892340/(1x394)

LCM = 53488892340/394

LCM = 135758610

Thus, we can understand that the LCM of 394,403,855,394 is 135758610.
