Given numbers are 911,221,911,191

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

The LCM of 911,221,911,191 is 38454221.

Find LCM of 911,221,911,191 with Prime Factorization

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

911 x 1 x 221 x 1 x 191 = 38454221

Therefore, the lowest common multiple of 911,221,911,191 is 38454221.

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.

911 x 221 x 911 x 191 = 35031795331

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.

911 : 1, 911

221 : 1, 13, 17, 221

911 : 1, 911

191 : 1, 191

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 911,221,911,191, is 1.

Now, the common factors can be found like this.

911:911

221:13x 17

911:911

191:191

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

911 = 911

Therefore, the value for common factors is 911.

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 = 35031795331/(1x911)

LCM = 35031795331/911

LCM = 38454221

Thus, we can understand that the LCM of 911,221,911,191 is 38454221.
