Given numbers are 687,850,816,663

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

The LCM of 687,850,816,663 is 60730800.

Find LCM of 687,850,816,663 with Prime Factorization

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

2 x 3 x 17 x 229 x 25 x 8 x 13 = 60730800

Therefore, the lowest common multiple of 687,850,816,663 is 60730800.

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.

687 x 850 x 816 x 663 = 315921621600

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.

687 : 1, 3, 229, 687

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

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

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,850,816,663, is 1.

Now, the common factors can be found like this.

687:3x 229

850:2x 5x 5x 17

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

663:3x 13x 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 17x 17 = 5202

Therefore, the value for common factors is 5202.

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 = 315921621600/(1x5202)

LCM = 315921621600/5202

LCM = 60730800

Thus, we can understand that the LCM of 687,850,816,663 is 60730800.
