Given numbers are 638,755,487,566

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

The LCM of 638,755,487,566 is 66386997490.

Find LCM of 638,755,487,566 with Prime Factorization

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

2 x 319 x 755 x 487 x 283 = 66386997490

Therefore, the lowest common multiple of 638,755,487,566 is 66386997490.

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 755 x 487 x 566 = 132773994980

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

755 : 1, 5, 151, 755

487 : 1, 487

566 : 1, 2, 283, 566

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,755,487,566, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

755:5x 151

487:487

566:2x 283

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

2 = 2

Therefore, the value for common factors is 2.

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 = 132773994980/(1x2)

LCM = 132773994980/2

LCM = 66386997490

Thus, we can understand that the LCM of 638,755,487,566 is 66386997490.
