Given numbers are 449,668,778,747

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

The LCM of 449,668,778,747 is 87155140356.

Find LCM of 449,668,778,747 with Prime Factorization

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

2 x 449 x 334 x 389 x 747 = 87155140356

Therefore, the lowest common multiple of 449,668,778,747 is 87155140356.

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.

449 x 668 x 778 x 747 = 174310280712

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.

449 : 1, 449

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

778 : 1, 2, 389, 778

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,668,778,747, is 1.

Now, the common factors can be found like this.

449:449

668:2x 2x 167

778:2x 389

747:3x 3x 83

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 = 174310280712/(1x2)

LCM = 174310280712/2

LCM = 87155140356

Thus, we can understand that the LCM of 449,668,778,747 is 87155140356.
