Given numbers are 728,121,104,938,522

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

The LCM of 728,121,104,938,522 is 1540394856.

Find LCM of 728,121,104,938,522 with Prime Factorization

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

2 x 2 x 2 x 7 x 13 x 1 x 121 x 1 x 67 x 261 = 1540394856

Therefore, the lowest common multiple of 728,121,104,938,522 is 1540394856.

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 121 x 104 x 938 x 522 = 4485629820672

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

121 : 1, 11, 121

104 : 1, 2, 4, 8, 13, 26, 52, 104

938 : 1, 2, 7, 14, 67, 134, 469, 938

522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,121,104,938,522, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

121:11x 11

104:2x 2x 2x 13

938:2x 7x 67

522:2x 3x 3x 29

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 2x 7x 13 = 2912

Therefore, the value for common factors is 2912.

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 = 4485629820672/(1x2912)

LCM = 4485629820672/2912

LCM = 1540394856

Thus, we can understand that the LCM of 728,121,104,938,522 is 1540394856.
