Given numbers are 660,403,798,664

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

The LCM of 660,403,798,664 is 5872306440.

Find LCM of 660,403,798,664 with Prime Factorization

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

2 x 2 x 3 x 55 x 403 x 133 x 166 = 5872306440

Therefore, the lowest common multiple of 660,403,798,664 is 5872306440.

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.

660 x 403 x 798 x 664 = 140935354560

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

403 : 1, 13, 31, 403

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

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 660,403,798,664, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

403:13x 31

798:2x 3x 7x 19

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 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 140935354560/(1x24)

LCM = 140935354560/24

LCM = 5872306440

Thus, we can understand that the LCM of 660,403,798,664 is 5872306440.
