Given numbers are 991,9910

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

The LCM of 991,9910 is 9910.

Find LCM of 991,9910 with Prime Factorization

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

991 x 1 x 10 = 9910

Therefore, the lowest common multiple of 991,9910 is 9910.

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.

991 x 9910 = 9820810

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.

991 : 1, 991

9910 : 1, 2, 5, 10, 991, 1982, 4955, 9910

991 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,9910, is 991.

Now, the common factors can be found like this.

991:991

9910:2x 5x 991

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 = 9820810/(991x1)

LCM = 9820810/991

LCM = 9910

Thus, we can understand that the LCM of 991,9910 is 9910.
