Given numbers are 217,209,171,913

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

The LCM of 217,209,171,913 is 33878691.

Find LCM of 217,209,171,913 with Prime Factorization

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

11 x 19 x 217 x 1 x 9 x 83 = 33878691

Therefore, the lowest common multiple of 217,209,171,913 is 33878691.

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.

217 x 209 x 171 x 913 = 7080646419

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.

217 : 1, 7, 31, 217

209 : 1, 11, 19, 209

171 : 1, 3, 9, 19, 57, 171

913 : 1, 11, 83, 913

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,209,171,913, is 1.

Now, the common factors can be found like this.

217:7x 31

209:11x 19

171:3x 3x 19

913:11x 83

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

11x 19 = 209

Therefore, the value for common factors is 209.

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 = 7080646419/(1x209)

LCM = 7080646419/209

LCM = 33878691

Thus, we can understand that the LCM of 217,209,171,913 is 33878691.
