Given numbers are 159,243,687,644

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

The LCM of 159,243,687,644 is 1899343404.

Find LCM of 159,243,687,644 with Prime Factorization

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

3 x 53 x 81 x 229 x 644 = 1899343404

Therefore, the lowest common multiple of 159,243,687,644 is 1899343404.

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.

159 x 243 x 687 x 644 = 17094090636

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.

159 : 1, 3, 53, 159

243 : 1, 3, 9, 27, 81, 243

687 : 1, 3, 229, 687

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,243,687,644, is 1.

Now, the common factors can be found like this.

159:3x 53

243:3x 3x 3x 3x 3

687:3x 229

644:2x 2x 7x 23

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 17094090636/(1x9)

LCM = 17094090636/9

LCM = 1899343404

Thus, we can understand that the LCM of 159,243,687,644 is 1899343404.
