Given numbers are 764,209,408,865

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

The LCM of 764,209,408,865 is 14088213480.

Find LCM of 764,209,408,865 with Prime Factorization

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

2 x 2 x 191 x 209 x 102 x 865 = 14088213480

Therefore, the lowest common multiple of 764,209,408,865 is 14088213480.

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.

764 x 209 x 408 x 865 = 56352853920

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.

764 : 1, 2, 4, 191, 382, 764

209 : 1, 11, 19, 209

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

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,209,408,865, is 1.

Now, the common factors can be found like this.

764:2x 2x 191

209:11x 19

408:2x 2x 2x 3x 17

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 56352853920/(1x4)

LCM = 56352853920/4

LCM = 14088213480

Thus, we can understand that the LCM of 764,209,408,865 is 14088213480.
