Given numbers are 115,521,161,731,711

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

The LCM of 115,521,161,731,711 is 217981974105.

Find LCM of 115,521,161,731,711 with Prime Factorization

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

23 x 5 x 521 x 7 x 731 x 711 = 217981974105

Therefore, the lowest common multiple of 115,521,161,731,711 is 217981974105.

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.

115 x 521 x 161 x 731 x 711 = 5013585404415

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.

115 : 1, 5, 23, 115

521 : 1, 521

161 : 1, 7, 23, 161

731 : 1, 17, 43, 731

711 : 1, 3, 9, 79, 237, 711

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,521,161,731,711, is 1.

Now, the common factors can be found like this.

115:5x 23

521:521

161:7x 23

731:17x 43

711:3x 3x 79

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 = 5013585404415/(1x23)

LCM = 5013585404415/23

LCM = 217981974105

Thus, we can understand that the LCM of 115,521,161,731,711 is 217981974105.
