Given numbers are 663,810,319,816

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

The LCM of 663,810,319,816 is 456833520.

Find LCM of 663,810,319,816 with Prime Factorization

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

2 x 3 x 17 x 13 x 135 x 319 x 8 = 456833520

Therefore, the lowest common multiple of 663,810,319,816 is 456833520.

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.

663 x 810 x 319 x 816 = 139791057120

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.

663 : 1, 3, 13, 17, 39, 51, 221, 663

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

319 : 1, 11, 29, 319

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,810,319,816, is 1.

Now, the common factors can be found like this.

663:3x 13x 17

810:2x 3x 3x 3x 3x 5

319:11x 29

816:2x 2x 2x 2x 3x 17

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 3x 17 = 306

Therefore, the value for common factors is 306.

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 = 139791057120/(1x306)

LCM = 139791057120/306

LCM = 456833520

Thus, we can understand that the LCM of 663,810,319,816 is 456833520.
