Given numbers are 923,819,728,173

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

The LCM of 923,819,728,173 is 80478216.

Find LCM of 923,819,728,173 with Prime Factorization

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

7 x 13 x 71 x 9 x 8 x 173 = 80478216

Therefore, the lowest common multiple of 923,819,728,173 is 80478216.

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.

923 x 819 x 728 x 173 = 95205729528

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.

923 : 1, 13, 71, 923

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

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

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,819,728,173, is 1.

Now, the common factors can be found like this.

923:13x 71

819:3x 3x 7x 13

728:2x 2x 2x 7x 13

173:173

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

7x 13x 13 = 1183

Therefore, the value for common factors is 1183.

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 = 95205729528/(1x1183)

LCM = 95205729528/1183

LCM = 80478216

Thus, we can understand that the LCM of 923,819,728,173 is 80478216.
