Given numbers are 431,721,309,257

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

The LCM of 431,721,309,257 is 239589021.

Find LCM of 431,721,309,257 with Prime Factorization

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

103 x 431 x 7 x 3 x 257 = 239589021

Therefore, the lowest common multiple of 431,721,309,257 is 239589021.

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.

431 x 721 x 309 x 257 = 24677669163

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.

431 : 1, 431

721 : 1, 7, 103, 721

309 : 1, 3, 103, 309

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,721,309,257, is 1.

Now, the common factors can be found like this.

431:431

721:7x 103

309:3x 103

257:257

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

103 = 103

Therefore, the value for common factors is 103.

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 = 24677669163/(1x103)

LCM = 24677669163/103

LCM = 239589021

Thus, we can understand that the LCM of 431,721,309,257 is 239589021.
