Given numbers are 311,117,639

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

The LCM of 311,117,639 is 2583477.

Find LCM of 311,117,639 with Prime Factorization

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

3 x 3 x 311 x 13 x 71 = 2583477

Therefore, the lowest common multiple of 311,117,639 is 2583477.

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.

311 x 117 x 639 = 23251293

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.

311 : 1, 311

117 : 1, 3, 9, 13, 39, 117

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,117,639, is 1.

Now, the common factors can be found like this.

311:311

117:3x 3x 13

639:3x 3x 71

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 23251293/(1x9)

LCM = 23251293/9

LCM = 2583477

Thus, we can understand that the LCM of 311,117,639 is 2583477.

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

• LCM of 952, 324, 897
• LCM of 462, 125, 785
