Given numbers are 7819,9905

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

The LCM of 7819,9905 is 11063885.

Find LCM of 7819,9905 with Prime Factorization

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

7 x 1117 x 1415 = 11063885

Therefore, the lowest common multiple of 7819,9905 is 11063885.

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.

7819 x 9905 = 77447195

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.

7819 : 1, 7, 1117, 7819

9905 : 1, 5, 7, 35, 283, 1415, 1981, 9905

7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7819,9905, is 7.

Now, the common factors can be found like this.

7819:7x 1117

9905:5x 7x 283

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

= 1

Therefore, the value for common factors is 1.

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 = 77447195/(7x1)

LCM = 77447195/7

LCM = 11063885

Thus, we can understand that the LCM of 7819,9905 is 11063885.
