Given numbers are 418,319,946,161

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

The LCM of 418,319,946,161 is 83920606.

Find LCM of 418,319,946,161 with Prime Factorization

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

2 x 11 x 19 x 29 x 43 x 161 = 83920606

Therefore, the lowest common multiple of 418,319,946,161 is 83920606.

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.

418 x 319 x 946 x 161 = 20308786652

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

319 : 1, 11, 29, 319

946 : 1, 2, 11, 22, 43, 86, 473, 946

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,319,946,161, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

319:11x 29

946:2x 11x 43

161:7x 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 11x 11 = 242

Therefore, the value for common factors is 242.

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 = 20308786652/(1x242)

LCM = 20308786652/242

LCM = 83920606

Thus, we can understand that the LCM of 418,319,946,161 is 83920606.
