Given numbers are 638,618,291,667,493

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

The LCM of 638,618,291,667,493 is 7477004634.

Find LCM of 638,618,291,667,493 with Prime Factorization

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

2 x 3 x 29 x 11 x 103 x 97 x 23 x 17 = 7477004634

Therefore, the lowest common multiple of 638,618,291,667,493 is 7477004634.

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 618 x 291 x 667 x 493 = 37728965383164

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

618 : 1, 2, 3, 6, 103, 206, 309, 618

291 : 1, 3, 97, 291

667 : 1, 23, 29, 667

493 : 1, 17, 29, 493

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,618,291,667,493, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

618:2x 3x 103

291:3x 97

667:23x 29

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.

2x 3x 29x 29 = 5046

Therefore, the value for common factors is 5046.

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 = 37728965383164/(1x5046)

LCM = 37728965383164/5046

LCM = 7477004634

Thus, we can understand that the LCM of 638,618,291,667,493 is 7477004634.
