Given numbers are 256,560,129,791

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

The LCM of 256,560,129,791 is 130609920.

Find LCM of 256,560,129,791 with Prime Factorization

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

2 x 2 x 2 x 2 x 7 x 16 x 5 x 129 x 113 = 130609920

Therefore, the lowest common multiple of 256,560,129,791 is 130609920.

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.

256 x 560 x 129 x 791 = 14628311040

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.

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

129 : 1, 3, 43, 129

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,560,129,791, is 1.

Now, the common factors can be found like this.

256:2x 2x 2x 2x 2x 2x 2x 2

560:2x 2x 2x 2x 5x 7

129:3x 43

791:7x 113

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

2x 2x 2x 2x 7 = 112

Therefore, the value for common factors is 112.

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 = 14628311040/(1x112)

LCM = 14628311040/112

LCM = 130609920

Thus, we can understand that the LCM of 256,560,129,791 is 130609920.
