Given numbers are 924,396,165,642

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

The LCM of 924,396,165,642 is 1483020.

Find LCM of 924,396,165,642 with Prime Factorization

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

2 x 2 x 3 x 11 x 7 x 3 x 5 x 107 = 1483020

Therefore, the lowest common multiple of 924,396,165,642 is 1483020.

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.

924 x 396 x 165 x 642 = 38760210720

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.

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

165 : 1, 3, 5, 11, 15, 33, 55, 165

642 : 1, 2, 3, 6, 107, 214, 321, 642

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,396,165,642, is 3.

Now, the common factors can be found like this.

924:2x 2x 3x 7x 11

396:2x 2x 3x 3x 11

165:3x 5x 11

642:2x 3x 107

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 3x 3x 11x 11 = 8712

Therefore, the value for common factors is 8712.

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 = 38760210720/(3x8712)

LCM = 38760210720/26136

LCM = 1483020

Thus, we can understand that the LCM of 924,396,165,642 is 1483020.
