Given numbers are 388,793,221,507

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

The LCM of 388,793,221,507 is 203994492.

Find LCM of 388,793,221,507 with Prime Factorization

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

13 x 388 x 61 x 17 x 39 = 203994492

Therefore, the lowest common multiple of 388,793,221,507 is 203994492.

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.

388 x 793 x 221 x 507 = 34475069148

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.

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

793 : 1, 13, 61, 793

221 : 1, 13, 17, 221

507 : 1, 3, 13, 39, 169, 507

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,793,221,507, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

793:13x 61

221:13x 17

507:3x 13x 13

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 34475069148/(1x169)

LCM = 34475069148/169

LCM = 203994492

Thus, we can understand that the LCM of 388,793,221,507 is 203994492.
