Given numbers are 445,105,515,197

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

The LCM of 445,105,515,197 is 189619395.

Find LCM of 445,105,515,197 with Prime Factorization

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

5 x 89 x 21 x 103 x 197 = 189619395

Therefore, the lowest common multiple of 445,105,515,197 is 189619395.

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.

445 x 105 x 515 x 197 = 4740484875

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.

445 : 1, 5, 89, 445

105 : 1, 3, 5, 7, 15, 21, 35, 105

515 : 1, 5, 103, 515

197 : 1, 197

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,105,515,197, is 1.

Now, the common factors can be found like this.

445:5x 89

105:3x 5x 7

515:5x 103

197:197

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 4740484875/(1x25)

LCM = 4740484875/25

LCM = 189619395

Thus, we can understand that the LCM of 445,105,515,197 is 189619395.
