Given numbers are 318,161,436,394

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

The LCM of 318,161,436,394 is 2198749308.

Find LCM of 318,161,436,394 with Prime Factorization

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

2 x 159 x 161 x 218 x 197 = 2198749308

Therefore, the lowest common multiple of 318,161,436,394 is 2198749308.

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.

318 x 161 x 436 x 394 = 8794997232

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.

318 : 1, 2, 3, 6, 53, 106, 159, 318

161 : 1, 7, 23, 161

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

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,161,436,394, is 1.

Now, the common factors can be found like this.

318:2x 3x 53

161:7x 23

436:2x 2x 109

394:2x 197

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 8794997232/(1x4)

LCM = 8794997232/4

LCM = 2198749308

Thus, we can understand that the LCM of 318,161,436,394 is 2198749308.
