Given numbers are 309,247,813

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

The LCM of 309,247,813 is 20683533.

Find LCM of 309,247,813 with Prime Factorization

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

3 x 103 x 247 x 271 = 20683533

Therefore, the lowest common multiple of 309,247,813 is 20683533.

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.

309 x 247 x 813 = 62050599

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.

309 : 1, 3, 103, 309

247 : 1, 13, 19, 247

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,247,813, is 1.

Now, the common factors can be found like this.

309:3x 103

247:13x 19

813:3x 271

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 = 62050599/(1x3)

LCM = 62050599/3

LCM = 20683533

Thus, we can understand that the LCM of 309,247,813 is 20683533.

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

• LCM of 315, 554, 460
• LCM of 203, 544, 325
