Given numbers are 331,135,638,206,641

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

The LCM of 331,135,638,206,641 is 1882251687690.

Find LCM of 331,135,638,206,641 with Prime Factorization

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

2 x 331 x 135 x 319 x 103 x 641 = 1882251687690

Therefore, the lowest common multiple of 331,135,638,206,641 is 1882251687690.

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.

331 x 135 x 638 x 206 x 641 = 3764503375380

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.

331 : 1, 331

135 : 1, 3, 5, 9, 15, 27, 45, 135

638 : 1, 2, 11, 22, 29, 58, 319, 638

206 : 1, 2, 103, 206

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,135,638,206,641, is 1.

Now, the common factors can be found like this.

331:331

135:3x 3x 3x 5

638:2x 11x 29

206:2x 103

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.

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 = 3764503375380/(1x2)

LCM = 3764503375380/2

LCM = 1882251687690

Thus, we can understand that the LCM of 331,135,638,206,641 is 1882251687690.
