Given numbers are 641,497,568,460

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

The LCM of 641,497,568,460 is 293090840.

Find LCM of 641,497,568,460 with Prime Factorization

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

2 x 2 x 71 x 641 x 7 x 2 x 115 = 293090840

Therefore, the lowest common multiple of 641,497,568,460 is 293090840.

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.

641 x 497 x 568 x 460 = 83237798560

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.

641 : 1, 641

497 : 1, 7, 71, 497

568 : 1, 2, 4, 8, 71, 142, 284, 568

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,497,568,460, is 1.

Now, the common factors can be found like this.

641:641

497:7x 71

568:2x 2x 2x 71

460:2x 2x 5x 23

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 71 = 284

Therefore, the value for common factors is 284.

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 = 83237798560/(1x284)

LCM = 83237798560/284

LCM = 293090840

Thus, we can understand that the LCM of 641,497,568,460 is 293090840.
