Given numbers are 662,639,439,778

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

The LCM of 662,639,439,778 is 72239206878.

Find LCM of 662,639,439,778 with Prime Factorization

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

2 x 331 x 639 x 439 x 389 = 72239206878

Therefore, the lowest common multiple of 662,639,439,778 is 72239206878.

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.

662 x 639 x 439 x 778 = 144478413756

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.

662 : 1, 2, 331, 662

639 : 1, 3, 9, 71, 213, 639

439 : 1, 439

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,639,439,778, is 1.

Now, the common factors can be found like this.

662:2x 331

639:3x 3x 71

439:439

778:2x 389

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

2 = 2

Therefore, the value for common factors is 2.

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 = 144478413756/(1x2)

LCM = 144478413756/2

LCM = 72239206878

Thus, we can understand that the LCM of 662,639,439,778 is 72239206878.
