Given numbers are 399,239,209,163

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

The LCM of 399,239,209,163 is 170982273.

Find LCM of 399,239,209,163 with Prime Factorization

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

19 x 21 x 239 x 11 x 163 = 170982273

Therefore, the lowest common multiple of 399,239,209,163 is 170982273.

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.

399 x 239 x 209 x 163 = 3248663187

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

239 : 1, 239

209 : 1, 11, 19, 209

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,239,209,163, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

239:239

209:11x 19

163:163

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

19 = 19

Therefore, the value for common factors is 19.

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 = 3248663187/(1x19)

LCM = 3248663187/19

LCM = 170982273

Thus, we can understand that the LCM of 399,239,209,163 is 170982273.
