Given numbers are 243,389,214,107

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

The LCM of 243,389,214,107 is 20228778.

Find LCM of 243,389,214,107 with Prime Factorization

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

107 x 243 x 389 x 2 x 1 = 20228778

Therefore, the lowest common multiple of 243,389,214,107 is 20228778.

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 389 x 214 x 107 = 2164479246

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

389 : 1, 389

214 : 1, 2, 107, 214

107 : 1, 107

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,389,214,107, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

389:389

214:2x 107

107:107

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

107 = 107

Therefore, the value for common factors is 107.

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 = 2164479246/(1x107)

LCM = 2164479246/107

LCM = 20228778

Thus, we can understand that the LCM of 243,389,214,107 is 20228778.
