Given numbers are 257,194,356,945

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

The LCM of 257,194,356,945 is 8386614180.

Find LCM of 257,194,356,945 with Prime Factorization

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

2 x 257 x 97 x 178 x 945 = 8386614180

Therefore, the lowest common multiple of 257,194,356,945 is 8386614180.

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 194 x 356 x 945 = 16773228360

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

194 : 1, 2, 97, 194

356 : 1, 2, 4, 89, 178, 356

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,194,356,945, is 1.

Now, the common factors can be found like this.

257:257

194:2x 97

356:2x 2x 89

945:3x 3x 3x 5x 7

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 = 16773228360/(1x2)

LCM = 16773228360/2

LCM = 8386614180

Thus, we can understand that the LCM of 257,194,356,945 is 8386614180.
