Given numbers are 128,431,579,699,438

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

The LCM of 128,431,579,699,438 is 543306104448.

Find LCM of 128,431,579,699,438 with Prime Factorization

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

2 x 3 x 64 x 431 x 193 x 233 x 73 = 543306104448

Therefore, the lowest common multiple of 128,431,579,699,438 is 543306104448.

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 431 x 579 x 699 x 438 = 9779509880064

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

431 : 1, 431

579 : 1, 3, 193, 579

699 : 1, 3, 233, 699

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,431,579,699,438, is 1.

Now, the common factors can be found like this.

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

431:431

579:3x 193

699:3x 233

438:2x 3x 73

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 3 = 18

Therefore, the value for common factors is 18.

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 = 9779509880064/(1x18)

LCM = 9779509880064/18

LCM = 543306104448

Thus, we can understand that the LCM of 128,431,579,699,438 is 543306104448.
