Given numbers are 921,189,644,589

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

The LCM of 921,189,644,589 is 3144150324.

Find LCM of 921,189,644,589 with Prime Factorization

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

3 x 7 x 307 x 9 x 92 x 589 = 3144150324

Therefore, the lowest common multiple of 921,189,644,589 is 3144150324.

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.

921 x 189 x 644 x 589 = 66027156804

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.

921 : 1, 3, 307, 921

189 : 1, 3, 7, 9, 21, 27, 63, 189

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

589 : 1, 19, 31, 589

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,189,644,589, is 1.

Now, the common factors can be found like this.

921:3x 307

189:3x 3x 3x 7

644:2x 2x 7x 23

589:19x 31

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 66027156804/(1x21)

LCM = 66027156804/21

LCM = 3144150324

Thus, we can understand that the LCM of 921,189,644,589 is 3144150324.
