Given numbers are 206,187,978,388

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

The LCM of 206,187,978,388 is 3654428052.

Find LCM of 206,187,978,388 with Prime Factorization

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

2 x 103 x 187 x 489 x 194 = 3654428052

Therefore, the lowest common multiple of 206,187,978,388 is 3654428052.

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.

206 x 187 x 978 x 388 = 14617712208

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.

206 : 1, 2, 103, 206

187 : 1, 11, 17, 187

978 : 1, 2, 3, 6, 163, 326, 489, 978

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 206,187,978,388, is 1.

Now, the common factors can be found like this.

206:2x 103

187:11x 17

978:2x 3x 163

388:2x 2x 97

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 14617712208/(1x4)

LCM = 14617712208/4

LCM = 3654428052

Thus, we can understand that the LCM of 206,187,978,388 is 3654428052.
