Given numbers are 891,991,991,635

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

The LCM of 891,991,991,635 is 560692935.

Find LCM of 891,991,991,635 with Prime Factorization

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

991 x 891 x 1 x 1 x 635 = 560692935

Therefore, the lowest common multiple of 891,991,991,635 is 560692935.

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.

891 x 991 x 991 x 635 = 555646698585

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

991 : 1, 991

991 : 1, 991

635 : 1, 5, 127, 635

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,991,991,635, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

991:991

991:991

635:5x 127

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

991 = 991

Therefore, the value for common factors is 991.

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 = 555646698585/(1x991)

LCM = 555646698585/991

LCM = 560692935

Thus, we can understand that the LCM of 891,991,991,635 is 560692935.
