Given numbers are 747,412,128,943

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

The LCM of 747,412,128,943 is 9287086464.

Find LCM of 747,412,128,943 with Prime Factorization

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

2 x 2 x 747 x 103 x 32 x 943 = 9287086464

Therefore, the lowest common multiple of 747,412,128,943 is 9287086464.

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.

747 x 412 x 128 x 943 = 37148345856

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.

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

412 : 1, 2, 4, 103, 206, 412

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

943 : 1, 23, 41, 943

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,412,128,943, is 1.

Now, the common factors can be found like this.

747:3x 3x 83

412:2x 2x 103

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

943:23x 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 = 37148345856/(1x4)

LCM = 37148345856/4

LCM = 9287086464

Thus, we can understand that the LCM of 747,412,128,943 is 9287086464.
