Given numbers are 669,519,647,997

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

The LCM of 669,519,647,997 is 74657193483.

Find LCM of 669,519,647,997 with Prime Factorization

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

3 x 223 x 173 x 647 x 997 = 74657193483

Therefore, the lowest common multiple of 669,519,647,997 is 74657193483.

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.

669 x 519 x 647 x 997 = 223971580449

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.

669 : 1, 3, 223, 669

519 : 1, 3, 173, 519

647 : 1, 647

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,519,647,997, is 1.

Now, the common factors can be found like this.

669:3x 223

519:3x 173

647:647

997:997

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

3 = 3

Therefore, the value for common factors is 3.

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 = 223971580449/(1x3)

LCM = 223971580449/3

LCM = 74657193483

Thus, we can understand that the LCM of 669,519,647,997 is 74657193483.
