Given numbers are 991,211,363,55

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

The LCM of 991,211,363,55 is 379518315.

Find LCM of 991,211,363,55 with Prime Factorization

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

11 x 991 x 211 x 33 x 5 = 379518315

Therefore, the lowest common multiple of 991,211,363,55 is 379518315.

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 211 x 363 x 55 = 4174701465

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

211 : 1, 211

363 : 1, 3, 11, 33, 121, 363

55 : 1, 5, 11, 55

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,211,363,55, is 1.

Now, the common factors can be found like this.

991:991

211:211

363:3x 11x 11

55:5x 11

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

11 = 11

Therefore, the value for common factors is 11.

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 = 4174701465/(1x11)

LCM = 4174701465/11

LCM = 379518315

Thus, we can understand that the LCM of 991,211,363,55 is 379518315.
