Given numbers are 189,639,668,205

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

The LCM of 189,639,668,205 is 1837597860.

Find LCM of 189,639,668,205 with Prime Factorization

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

3 x 3 x 21 x 71 x 668 x 205 = 1837597860

Therefore, the lowest common multiple of 189,639,668,205 is 1837597860.

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.

189 x 639 x 668 x 205 = 16538380740

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.

189 : 1, 3, 7, 9, 21, 27, 63, 189

639 : 1, 3, 9, 71, 213, 639

668 : 1, 2, 4, 167, 334, 668

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,639,668,205, is 1.

Now, the common factors can be found like this.

189:3x 3x 3x 7

639:3x 3x 71

668:2x 2x 167

205:5x 41

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 16538380740/(1x9)

LCM = 16538380740/9

LCM = 1837597860

Thus, we can understand that the LCM of 189,639,668,205 is 1837597860.
