Given numbers are 287,913,173,865

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

The LCM of 287,913,173,865 is 226656815.

Find LCM of 287,913,173,865 with Prime Factorization

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

173 x 287 x 913 x 1 x 5 = 226656815

Therefore, the lowest common multiple of 287,913,173,865 is 226656815.

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.

287 x 913 x 173 x 865 = 39211628995

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.

287 : 1, 7, 41, 287

913 : 1, 11, 83, 913

173 : 1, 173

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,913,173,865, is 1.

Now, the common factors can be found like this.

287:7x 41

913:11x 83

173:173

865:5x 173

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

173 = 173

Therefore, the value for common factors is 173.

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 = 39211628995/(1x173)

LCM = 39211628995/173

LCM = 226656815

Thus, we can understand that the LCM of 287,913,173,865 is 226656815.
