Given numbers are 747,801,228,421

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

The LCM of 747,801,228,421 is 2127190068.

Find LCM of 747,801,228,421 with Prime Factorization

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

3 x 3 x 83 x 89 x 76 x 421 = 2127190068

Therefore, the lowest common multiple of 747,801,228,421 is 2127190068.

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 801 x 228 x 421 = 57434131836

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

801 : 1, 3, 9, 89, 267, 801

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,801,228,421, is 1.

Now, the common factors can be found like this.

747:3x 3x 83

801:3x 3x 89

228:2x 2x 3x 19

421:421

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 57434131836/(1x27)

LCM = 57434131836/27

LCM = 2127190068

Thus, we can understand that the LCM of 747,801,228,421 is 2127190068.
