Given numbers are 394,139,556,398

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

The LCM of 394,139,556,398 is 21796868.

Find LCM of 394,139,556,398 with Prime Factorization

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

2 x 139 x 197 x 1 x 2 x 199 = 21796868

Therefore, the lowest common multiple of 394,139,556,398 is 21796868.

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 139 x 556 x 398 = 12119058608

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

139 : 1, 139

556 : 1, 2, 4, 139, 278, 556

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,139,556,398, is 1.

Now, the common factors can be found like this.

394:2x 197

139:139

556:2x 2x 139

398:2x 199

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

2x 2x 139 = 556

Therefore, the value for common factors is 556.

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 = 12119058608/(1x556)

LCM = 12119058608/556

LCM = 21796868

Thus, we can understand that the LCM of 394,139,556,398 is 21796868.
