Given numbers are 638,659,526,538

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

The LCM of 638,659,526,538 is 29745010174.

Find LCM of 638,659,526,538 with Prime Factorization

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

2 x 319 x 659 x 263 x 269 = 29745010174

Therefore, the lowest common multiple of 638,659,526,538 is 29745010174.

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 659 x 526 x 538 = 118980040696

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

659 : 1, 659

526 : 1, 2, 263, 526

538 : 1, 2, 269, 538

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,659,526,538, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

659:659

526:2x 263

538:2x 269

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 = 118980040696/(1x4)

LCM = 118980040696/4

LCM = 29745010174

Thus, we can understand that the LCM of 638,659,526,538 is 29745010174.
