Given numbers are 123,840,732,395

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

The LCM of 123,840,732,395 is 165966360.

Find LCM of 123,840,732,395 with Prime Factorization

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

2 x 2 x 3 x 5 x 41 x 14 x 61 x 79 = 165966360

Therefore, the lowest common multiple of 123,840,732,395 is 165966360.

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.

123 x 840 x 732 x 395 = 29873944800

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.

123 : 1, 3, 41, 123

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,840,732,395, is 1.

Now, the common factors can be found like this.

123:3x 41

840:2x 2x 2x 3x 5x 7

732:2x 2x 3x 61

395:5x 79

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 29873944800/(1x180)

LCM = 29873944800/180

LCM = 165966360

Thus, we can understand that the LCM of 123,840,732,395 is 165966360.
