Given numbers are 409,232,162,861,391

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

The LCM of 409,232,162,861,391 is 862491782376.

Find LCM of 409,232,162,861,391 with Prime Factorization

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

2 x 3 x 409 x 116 x 27 x 287 x 391 = 862491782376

Therefore, the lowest common multiple of 409,232,162,861,391 is 862491782376.

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.

409 x 232 x 162 x 861 x 391 = 5174950694256

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.

409 : 1, 409

232 : 1, 2, 4, 8, 29, 58, 116, 232

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

861 : 1, 3, 7, 21, 41, 123, 287, 861

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,232,162,861,391, is 1.

Now, the common factors can be found like this.

409:409

232:2x 2x 2x 29

162:2x 3x 3x 3x 3

861:3x 7x 41

391:17x 23

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 = 5174950694256/(1x6)

LCM = 5174950694256/6

LCM = 862491782376

Thus, we can understand that the LCM of 409,232,162,861,391 is 862491782376.
