Given numbers are 405,257,949,436,258

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

The LCM of 405,257,949,436,258 is 1851864915420.

Find LCM of 405,257,949,436,258 with Prime Factorization

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

2 x 3 x 135 x 257 x 949 x 218 x 43 = 1851864915420

Therefore, the lowest common multiple of 405,257,949,436,258 is 1851864915420.

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.

405 x 257 x 949 x 436 x 258 = 11111189492520

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.

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

257 : 1, 257

949 : 1, 13, 73, 949

436 : 1, 2, 4, 109, 218, 436

258 : 1, 2, 3, 6, 43, 86, 129, 258

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,257,949,436,258, is 1.

Now, the common factors can be found like this.

405:3x 3x 3x 3x 5

257:257

949:13x 73

436:2x 2x 109

258:2x 3x 43

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 11111189492520/(1x6)

LCM = 11111189492520/6

LCM = 1851864915420

Thus, we can understand that the LCM of 405,257,949,436,258 is 1851864915420.
