Given numbers are 685,789,309

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

The LCM of 685,789,309 is 55667895.

Find LCM of 685,789,309 with Prime Factorization

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

3 x 685 x 263 x 103 = 55667895

Therefore, the lowest common multiple of 685,789,309 is 55667895.

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.

685 x 789 x 309 = 167003685

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.

685 : 1, 5, 137, 685

789 : 1, 3, 263, 789

309 : 1, 3, 103, 309

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,789,309, is 1.

Now, the common factors can be found like this.

685:5x 137

789:3x 263

309:3x 103

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

3 = 3

Therefore, the value for common factors is 3.

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 = 167003685/(1x3)

LCM = 167003685/3

LCM = 55667895

Thus, we can understand that the LCM of 685,789,309 is 55667895.

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

• LCM of 248, 445, 903
• LCM of 220, 248, 362
