Given numbers are 728,856,942,121

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

The LCM of 728,856,942,121 is 4439370936.

Find LCM of 728,856,942,121 with Prime Factorization

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

2 x 2 x 2 x 91 x 107 x 471 x 121 = 4439370936

Therefore, the lowest common multiple of 728,856,942,121 is 4439370936.

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 856 x 942 x 121 = 71029934976

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

856 : 1, 2, 4, 8, 107, 214, 428, 856

942 : 1, 2, 3, 6, 157, 314, 471, 942

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,856,942,121, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

856:2x 2x 2x 107

942:2x 3x 157

121:11x 11

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 2 = 16

Therefore, the value for common factors is 16.

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 = 71029934976/(1x16)

LCM = 71029934976/16

LCM = 4439370936

Thus, we can understand that the LCM of 728,856,942,121 is 4439370936.
