Given numbers are 642,654,543,497

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

The LCM of 642,654,543,497 is 6295010946.

Find LCM of 642,654,543,497 with Prime Factorization

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

2 x 3 x 107 x 109 x 181 x 497 = 6295010946

Therefore, the lowest common multiple of 642,654,543,497 is 6295010946.

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.

642 x 654 x 543 x 497 = 113310197028

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

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

543 : 1, 3, 181, 543

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,654,543,497, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

654:2x 3x 109

543:3x 181

497:7x 71

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 3 = 18

Therefore, the value for common factors is 18.

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 = 113310197028/(1x18)

LCM = 113310197028/18

LCM = 6295010946

Thus, we can understand that the LCM of 642,654,543,497 is 6295010946.
