Given numbers are 487,654,641,872

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

The LCM of 487,654,641,872 is 816628872.

Find LCM of 487,654,641,872 with Prime Factorization

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

2 x 109 x 487 x 3 x 641 x 4 = 816628872

Therefore, the lowest common multiple of 487,654,641,872 is 816628872.

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.

487 x 654 x 641 x 872 = 178025094096

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.

487 : 1, 487

654 : 1, 2, 3, 6, 109, 218, 327, 654

641 : 1, 641

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,654,641,872, is 1.

Now, the common factors can be found like this.

487:487

654:2x 3x 109

641:641

872:2x 2x 2x 109

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

2x 109 = 218

Therefore, the value for common factors is 218.

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 = 178025094096/(1x218)

LCM = 178025094096/218

LCM = 816628872

Thus, we can understand that the LCM of 487,654,641,872 is 816628872.
