Given numbers are 161,161,866,393

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

The LCM of 161,161,866,393 is 54794418.

Find LCM of 161,161,866,393 with Prime Factorization

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

7 x 23 x 1 x 1 x 866 x 393 = 54794418

Therefore, the lowest common multiple of 161,161,866,393 is 54794418.

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 161 x 866 x 393 = 8821901298

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

161 : 1, 7, 23, 161

866 : 1, 2, 433, 866

393 : 1, 3, 131, 393

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,161,866,393, is 1.

Now, the common factors can be found like this.

161:7x 23

161:7x 23

866:2x 433

393:3x 131

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 8821901298/(1x161)

LCM = 8821901298/161

LCM = 54794418

Thus, we can understand that the LCM of 161,161,866,393 is 54794418.
