Given numbers are 309,159,781

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

The LCM of 309,159,781 is 12790437.

Find LCM of 309,159,781 with Prime Factorization

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

3 x 103 x 53 x 781 = 12790437

Therefore, the lowest common multiple of 309,159,781 is 12790437.

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 159 x 781 = 38371311

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

159 : 1, 3, 53, 159

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,159,781, is 1.

Now, the common factors can be found like this.

309:3x 103

159:3x 53

781:11x 71

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 = 38371311/(1x3)

LCM = 38371311/3

LCM = 12790437

Thus, we can understand that the LCM of 309,159,781 is 12790437.

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

• LCM of 185, 568, 471
• LCM of 191, 872, 987
• LCM of 176, 123, 139
