Given numbers are 257,313,351,673,728

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

The LCM of 257,313,351,673,728 is 1064112803208.

Find LCM of 257,313,351,673,728 with Prime Factorization

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

13 x 257 x 313 x 27 x 673 x 56 = 1064112803208

Therefore, the lowest common multiple of 257,313,351,673,728 is 1064112803208.

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.

257 x 313 x 351 x 673 x 728 = 13833466441704

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.

257 : 1, 257

313 : 1, 313

351 : 1, 3, 9, 13, 27, 39, 117, 351

673 : 1, 673

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,313,351,673,728, is 1.

Now, the common factors can be found like this.

257:257

313:313

351:3x 3x 3x 13

673:673

728:2x 2x 2x 7x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 13833466441704/(1x13)

LCM = 13833466441704/13

LCM = 1064112803208

Thus, we can understand that the LCM of 257,313,351,673,728 is 1064112803208.
