Given numbers are 128,909,739,747

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

The LCM of 128,909,739,747 is 7136682624.

Find LCM of 128,909,739,747 with Prime Factorization

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

3 x 3 x 128 x 101 x 739 x 83 = 7136682624

Therefore, the lowest common multiple of 128,909,739,747 is 7136682624.

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.

128 x 909 x 739 x 747 = 64230143616

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

909 : 1, 3, 9, 101, 303, 909

739 : 1, 739

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 128,909,739,747, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

909:3x 3x 101

739:739

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.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 64230143616/(1x9)

LCM = 64230143616/9

LCM = 7136682624

Thus, we can understand that the LCM of 128,909,739,747 is 7136682624.
