Given numbers are 648,207,503,865

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

The LCM of 648,207,503,865 is 6484655880.

Find LCM of 648,207,503,865 with Prime Factorization

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

3 x 3 x 72 x 23 x 503 x 865 = 6484655880

Therefore, the lowest common multiple of 648,207,503,865 is 6484655880.

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.

648 x 207 x 503 x 865 = 58361902920

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

207 : 1, 3, 9, 23, 69, 207

503 : 1, 503

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,207,503,865, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

207:3x 3x 23

503:503

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.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 58361902920/(1x9)

LCM = 58361902920/9

LCM = 6484655880

Thus, we can understand that the LCM of 648,207,503,865 is 6484655880.
