Given numbers are 243,421,191,955

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

The LCM of 243,421,191,955 is 97699365.

Find LCM of 243,421,191,955 with Prime Factorization

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

191 x 243 x 421 x 1 x 5 = 97699365

Therefore, the lowest common multiple of 243,421,191,955 is 97699365.

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.

243 x 421 x 191 x 955 = 18660578715

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.

243 : 1, 3, 9, 27, 81, 243

421 : 1, 421

191 : 1, 191

955 : 1, 5, 191, 955

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,421,191,955, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

421:421

191:191

955:5x 191

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

191 = 191

Therefore, the value for common factors is 191.

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 = 18660578715/(1x191)

LCM = 18660578715/191

LCM = 97699365

Thus, we can understand that the LCM of 243,421,191,955 is 97699365.
