Given numbers are 6,640,491,523

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

The LCM of 6,640,491,523 is 493042560.

Find LCM of 6,640,491,523 with Prime Factorization

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

2 x 3 x 320 x 491 x 523 = 493042560

Therefore, the lowest common multiple of 6,640,491,523 is 493042560.

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.

6 x 640 x 491 x 523 = 986085120

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.

6 : 1, 2, 3, 6

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

491 : 1, 491

523 : 1, 523

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6,640,491,523, is 1.

Now, the common factors can be found like this.

6:2x 3

640:2x 2x 2x 2x 2x 2x 2x 5

491:491

523:523

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 = 986085120/(1x2)

LCM = 986085120/2

LCM = 493042560

Thus, we can understand that the LCM of 6,640,491,523 is 493042560.
