Given numbers are 161,731,529,691

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

The LCM of 161,731,529,691 is 1870463063.

Find LCM of 161,731,529,691 with Prime Factorization

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

23 x 7 x 731 x 23 x 691 = 1870463063

Therefore, the lowest common multiple of 161,731,529,691 is 1870463063.

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 731 x 529 x 691 = 43020650449

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

731 : 1, 17, 43, 731

529 : 1, 23, 529

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,731,529,691, is 1.

Now, the common factors can be found like this.

161:7x 23

731:17x 43

529:23x 23

691:691

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

23 = 23

Therefore, the value for common factors is 23.

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 = 43020650449/(1x23)

LCM = 43020650449/23

LCM = 1870463063

Thus, we can understand that the LCM of 161,731,529,691 is 1870463063.
