Given numbers are 638,839,231,493

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

The LCM of 638,839,231,493 is 191095674.

Find LCM of 638,839,231,493 with Prime Factorization

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

11 x 29 x 2 x 839 x 21 x 17 = 191095674

Therefore, the lowest common multiple of 638,839,231,493 is 191095674.

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.

638 x 839 x 231 x 493 = 60959520006

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

839 : 1, 839

231 : 1, 3, 7, 11, 21, 33, 77, 231

493 : 1, 17, 29, 493

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,839,231,493, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

839:839

231:3x 7x 11

493:17x 29

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

11x 29 = 319

Therefore, the value for common factors is 319.

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 = 60959520006/(1x319)

LCM = 60959520006/319

LCM = 191095674

Thus, we can understand that the LCM of 638,839,231,493 is 191095674.
