Given numbers are 806,642,497,664

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

The LCM of 806,642,497,664 is 42690824904.

Find LCM of 806,642,497,664 with Prime Factorization

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

2 x 403 x 321 x 497 x 332 = 42690824904

Therefore, the lowest common multiple of 806,642,497,664 is 42690824904.

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.

806 x 642 x 497 x 664 = 170763299616

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.

806 : 1, 2, 13, 26, 31, 62, 403, 806

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

497 : 1, 7, 71, 497

664 : 1, 2, 4, 8, 83, 166, 332, 664

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,642,497,664, is 1.

Now, the common factors can be found like this.

806:2x 13x 31

642:2x 3x 107

497:7x 71

664:2x 2x 2x 83

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 170763299616/(1x4)

LCM = 170763299616/4

LCM = 42690824904

Thus, we can understand that the LCM of 806,642,497,664 is 42690824904.
