Given numbers are 161,235,391,323

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

The LCM of 161,235,391,323 is 12220705.

Find LCM of 161,235,391,323 with Prime Factorization

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

17 x 23 x 7 x 235 x 1 x 19 = 12220705

Therefore, the lowest common multiple of 161,235,391,323 is 12220705.

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.

161 x 235 x 391 x 323 = 4778295655

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.

161 : 1, 7, 23, 161

235 : 1, 5, 47, 235

391 : 1, 17, 23, 391

323 : 1, 17, 19, 323

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,235,391,323, is 1.

Now, the common factors can be found like this.

161:7x 23

235:5x 47

391:17x 23

323:17x 19

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

17x 23 = 391

Therefore, the value for common factors is 391.

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 = 4778295655/(1x391)

LCM = 4778295655/391

LCM = 12220705

Thus, we can understand that the LCM of 161,235,391,323 is 12220705.
