Given numbers are 665,772,865,815

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

The LCM of 665,772,865,815 is 14476802620.

Find LCM of 665,772,865,815 with Prime Factorization

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

5 x 133 x 772 x 173 x 163 = 14476802620

Therefore, the lowest common multiple of 665,772,865,815 is 14476802620.

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.

665 x 772 x 865 x 815 = 361920065500

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

772 : 1, 2, 4, 193, 386, 772

865 : 1, 5, 173, 865

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,772,865,815, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

772:2x 2x 193

865:5x 173

815:5x 163

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 361920065500/(1x25)

LCM = 361920065500/25

LCM = 14476802620

Thus, we can understand that the LCM of 665,772,865,815 is 14476802620.
