Given numbers are 561,391,163,352

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

The LCM of 561,391,163,352 is 67302048.

Find LCM of 561,391,163,352 with Prime Factorization

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

11 x 17 x 3 x 23 x 163 x 32 = 67302048

Therefore, the lowest common multiple of 561,391,163,352 is 67302048.

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.

561 x 391 x 163 x 352 = 12585482976

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

391 : 1, 17, 23, 391

163 : 1, 163

352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,391,163,352, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

391:17x 23

163:163

352:2x 2x 2x 2x 2x 11

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

11x 17 = 187

Therefore, the value for common factors is 187.

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 = 12585482976/(1x187)

LCM = 12585482976/187

LCM = 67302048

Thus, we can understand that the LCM of 561,391,163,352 is 67302048.
