Given numbers are 687,517,128,803

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

The LCM of 687,517,128,803 is 3318792576.

Find LCM of 687,517,128,803 with Prime Factorization

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

11 x 687 x 47 x 128 x 73 = 3318792576

Therefore, the lowest common multiple of 687,517,128,803 is 3318792576.

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 517 x 128 x 803 = 36506718336

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

517 : 1, 11, 47, 517

128 : 1, 2, 4, 8, 16, 32, 64, 128

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,517,128,803, is 1.

Now, the common factors can be found like this.

687:3x 229

517:11x 47

128:2x 2x 2x 2x 2x 2x 2

803:11x 73

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

11 = 11

Therefore, the value for common factors is 11.

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 = 36506718336/(1x11)

LCM = 36506718336/11

LCM = 3318792576

Thus, we can understand that the LCM of 687,517,128,803 is 3318792576.
