Given numbers are 447,734,642,993,747

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

The LCM of 447,734,642,993,747 is 2893441469634.

Find LCM of 447,734,642,993,747 with Prime Factorization

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

2 x 3 x 149 x 367 x 107 x 331 x 249 = 2893441469634

Therefore, the lowest common multiple of 447,734,642,993,747 is 2893441469634.

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.

447 x 734 x 642 x 993 x 747 = 156245839360236

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.

447 : 1, 3, 149, 447

734 : 1, 2, 367, 734

642 : 1, 2, 3, 6, 107, 214, 321, 642

993 : 1, 3, 331, 993

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 447,734,642,993,747, is 1.

Now, the common factors can be found like this.

447:3x 149

734:2x 367

642:2x 3x 107

993:3x 331

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.

2x 3x 3x 3 = 54

Therefore, the value for common factors is 54.

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 = 156245839360236/(1x54)

LCM = 156245839360236/54

LCM = 2893441469634

Thus, we can understand that the LCM of 447,734,642,993,747 is 2893441469634.
