Given numbers are 311,538,842

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

The LCM of 311,538,842 is 70440878.

Find LCM of 311,538,842 with Prime Factorization

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

2 x 311 x 269 x 421 = 70440878

Therefore, the lowest common multiple of 311,538,842 is 70440878.

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 538 x 842 = 140881756

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

538 : 1, 2, 269, 538

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,538,842, is 1.

Now, the common factors can be found like this.

311:311

538:2x 269

842:2x 421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 140881756/(1x2)

LCM = 140881756/2

LCM = 70440878

Thus, we can understand that the LCM of 311,538,842 is 70440878.

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

• LCM of 282, 161, 252
