Given numbers are 668,454,997,574

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

The LCM of 668,454,997,574 is 43388973404.

Find LCM of 668,454,997,574 with Prime Factorization

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

2 x 334 x 227 x 997 x 287 = 43388973404

Therefore, the lowest common multiple of 668,454,997,574 is 43388973404.

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.

668 x 454 x 997 x 574 = 173555893616

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.

668 : 1, 2, 4, 167, 334, 668

454 : 1, 2, 227, 454

997 : 1, 997

574 : 1, 2, 7, 14, 41, 82, 287, 574

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,454,997,574, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

454:2x 227

997:997

574:2x 7x 41

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 = 173555893616/(1x4)

LCM = 173555893616/4

LCM = 43388973404

Thus, we can understand that the LCM of 668,454,997,574 is 43388973404.
