Given numbers are 997,382,438,388

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

The LCM of 997,382,438,388 is 16180963044.

Find LCM of 997,382,438,388 with Prime Factorization

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

2 x 997 x 191 x 219 x 194 = 16180963044

Therefore, the lowest common multiple of 997,382,438,388 is 16180963044.

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.

997 x 382 x 438 x 388 = 64723852176

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.

997 : 1, 997

382 : 1, 2, 191, 382

438 : 1, 2, 3, 6, 73, 146, 219, 438

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,382,438,388, is 1.

Now, the common factors can be found like this.

997:997

382:2x 191

438:2x 3x 73

388:2x 2x 97

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 64723852176/(1x4)

LCM = 64723852176/4

LCM = 16180963044

Thus, we can understand that the LCM of 997,382,438,388 is 16180963044.
