Given numbers are 438,171,511,195

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

The LCM of 438,171,511,195 is 11359530.

Find LCM of 438,171,511,195 with Prime Factorization

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

3 x 73 x 2 x 57 x 7 x 65 = 11359530

Therefore, the lowest common multiple of 438,171,511,195 is 11359530.

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.

438 x 171 x 511 x 195 = 7463211210

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

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

511 : 1, 7, 73, 511

195 : 1, 3, 5, 13, 15, 39, 65, 195

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,171,511,195, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

171:3x 3x 19

511:7x 73

195:3x 5x 13

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 73 = 657

Therefore, the value for common factors is 657.

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 = 7463211210/(1x657)

LCM = 7463211210/657

LCM = 11359530

Thus, we can understand that the LCM of 438,171,511,195 is 11359530.
