Given numbers are 638,538,691,290

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

The LCM of 638,538,691,290 is 592954010.

Find LCM of 638,538,691,290 with Prime Factorization

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

2 x 29 x 11 x 269 x 691 x 5 = 592954010

Therefore, the lowest common multiple of 638,538,691,290 is 592954010.

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 538 x 691 x 290 = 68782665160

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

538 : 1, 2, 269, 538

691 : 1, 691

290 : 1, 2, 5, 10, 29, 58, 145, 290

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,538,691,290, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

538:2x 269

691:691

290:2x 5x 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 2x 29 = 116

Therefore, the value for common factors is 116.

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 = 68782665160/(1x116)

LCM = 68782665160/116

LCM = 592954010

Thus, we can understand that the LCM of 638,538,691,290 is 592954010.
