Given numbers are 728,936,121,903,934

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

The LCM of 728,936,121,903,934 is 15920056152.

Find LCM of 728,936,121,903,934 with Prime Factorization

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

2 x 2 x 2 x 3 x 7 x 13 x 1 x 3 x 121 x 43 x 467 = 15920056152

Therefore, the lowest common multiple of 728,936,121,903,934 is 15920056152.

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.

728 x 936 x 121 x 903 x 934 = 69538805271936

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

121 : 1, 11, 121

903 : 1, 3, 7, 21, 43, 129, 301, 903

934 : 1, 2, 467, 934

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,936,121,903,934, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

936:2x 2x 2x 3x 3x 13

121:11x 11

903:3x 7x 43

934:2x 467

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 3x 7x 13 = 4368

Therefore, the value for common factors is 4368.

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 = 69538805271936/(1x4368)

LCM = 69538805271936/4368

LCM = 15920056152

Thus, we can understand that the LCM of 728,936,121,903,934 is 15920056152.
