Given numbers are 321,428,311,641

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

The LCM of 321,428,311,641 is 255966684.

Find LCM of 321,428,311,641 with Prime Factorization

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

107 x 3 x 4 x 311 x 641 = 255966684

Therefore, the lowest common multiple of 321,428,311,641 is 255966684.

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.

321 x 428 x 311 x 641 = 27388435188

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.

321 : 1, 3, 107, 321

428 : 1, 2, 4, 107, 214, 428

311 : 1, 311

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,428,311,641, is 1.

Now, the common factors can be found like this.

321:3x 107

428:2x 2x 107

311:311

641:641

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

107 = 107

Therefore, the value for common factors is 107.

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 = 27388435188/(1x107)

LCM = 27388435188/107

LCM = 255966684

Thus, we can understand that the LCM of 321,428,311,641 is 255966684.
