Given numbers are 161,930,393,393,173

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

The LCM of 161,930,393,393,173 is 3393330990.

Find LCM of 161,930,393,393,173 with Prime Factorization

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

3 x 131 x 161 x 310 x 1 x 1 x 173 = 3393330990

Therefore, the lowest common multiple of 161,930,393,393,173 is 3393330990.

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 930 x 393 x 393 x 173 = 4000737237210

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

930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930

393 : 1, 3, 131, 393

393 : 1, 3, 131, 393

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,930,393,393,173, is 1.

Now, the common factors can be found like this.

161:7x 23

930:2x 3x 5x 31

393:3x 131

393:3x 131

173:173

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

3x 3x 131 = 1179

Therefore, the value for common factors is 1179.

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 = 4000737237210/(1x1179)

LCM = 4000737237210/1179

LCM = 3393330990

Thus, we can understand that the LCM of 161,930,393,393,173 is 3393330990.
