Given numbers are 243,458,257,916

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

The LCM of 243,458,257,916 is 57205116.

Find LCM of 243,458,257,916 with Prime Factorization

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

2 x 229 x 243 x 1 x 257 x 2 = 57205116

Therefore, the lowest common multiple of 243,458,257,916 is 57205116.

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.

243 x 458 x 257 x 916 = 26199943128

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.

243 : 1, 3, 9, 27, 81, 243

458 : 1, 2, 229, 458

257 : 1, 257

916 : 1, 2, 4, 229, 458, 916

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,458,257,916, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

458:2x 229

257:257

916:2x 2x 229

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

2x 229 = 458

Therefore, the value for common factors is 458.

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 = 26199943128/(1x458)

LCM = 26199943128/458

LCM = 57205116

Thus, we can understand that the LCM of 243,458,257,916 is 57205116.
