Given numbers are 81,69,24,39,437

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

The LCM of 81,69,24,39,437 is 3681288.

Find LCM of 81,69,24,39,437 with Prime Factorization

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

3 x 23 x 27 x 1 x 8 x 13 x 19 = 3681288

Therefore, the lowest common multiple of 81,69,24,39,437 is 3681288.

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.

81 x 69 x 24 x 39 x 437 = 2286079848

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.

81 : 1, 3, 9, 27, 81

69 : 1, 3, 23, 69

24 : 1, 2, 3, 4, 6, 8, 12, 24

39 : 1, 3, 13, 39

437 : 1, 19, 23, 437

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 81,69,24,39,437, is 1.

Now, the common factors can be found like this.

81:3x 3x 3x 3

69:3x 23

24:2x 2x 2x 3

39:3x 13

437:19x 23

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

3x 3x 3x 23 = 621

Therefore, the value for common factors is 621.

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 = 2286079848/(1x621)

LCM = 2286079848/621

LCM = 3681288

Thus, we can understand that the LCM of 81,69,24,39,437 is 3681288.
