Given numbers are 789,161,579,621

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

The LCM of 789,161,579,621 is 220649373.

Find LCM of 789,161,579,621 with Prime Factorization

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

3 x 23 x 263 x 7 x 193 x 9 = 220649373

Therefore, the lowest common multiple of 789,161,579,621 is 220649373.

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.

789 x 161 x 579 x 621 = 45674420211

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.

789 : 1, 3, 263, 789

161 : 1, 7, 23, 161

579 : 1, 3, 193, 579

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,161,579,621, is 1.

Now, the common factors can be found like this.

789:3x 263

161:7x 23

579:3x 193

621:3x 3x 3x 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 3x 23 = 207

Therefore, the value for common factors is 207.

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 = 45674420211/(1x207)

LCM = 45674420211/207

LCM = 220649373

Thus, we can understand that the LCM of 789,161,579,621 is 220649373.
