Given numbers are 845,215,789

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

The LCM of 845,215,789 is 28668315.

Find LCM of 845,215,789 with Prime Factorization

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

5 x 169 x 43 x 789 = 28668315

Therefore, the lowest common multiple of 845,215,789 is 28668315.

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.

845 x 215 x 789 = 143341575

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.

845 : 1, 5, 13, 65, 169, 845

215 : 1, 5, 43, 215

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,215,789, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

215:5x 43

789:3x 263

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

5 = 5

Therefore, the value for common factors is 5.

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 = 143341575/(1x5)

LCM = 143341575/5

LCM = 28668315

Thus, we can understand that the LCM of 845,215,789 is 28668315.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 525, 502, 562
• LCM of 790, 345, 100
