Given numbers are 297,543,220,161

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

The LCM of 297,543,220,161 is 173097540.

Find LCM of 297,543,220,161 with Prime Factorization

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

3 x 11 x 9 x 181 x 20 x 161 = 173097540

Therefore, the lowest common multiple of 297,543,220,161 is 173097540.

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.

297 x 543 x 220 x 161 = 5712218820

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.

297 : 1, 3, 9, 11, 27, 33, 99, 297

543 : 1, 3, 181, 543

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,543,220,161, is 1.

Now, the common factors can be found like this.

297:3x 3x 3x 11

543:3x 181

220:2x 2x 5x 11

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.

3x 11 = 33

Therefore, the value for common factors is 33.

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 = 5712218820/(1x33)

LCM = 5712218820/33

LCM = 173097540

Thus, we can understand that the LCM of 297,543,220,161 is 173097540.
