Given numbers are 206,456,647,647

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

The LCM of 206,456,647,647 is 30388296.

Find LCM of 206,456,647,647 with Prime Factorization

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

2 x 647 x 103 x 228 x 1 x 1 = 30388296

Therefore, the lowest common multiple of 206,456,647,647 is 30388296.

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 456 x 647 x 647 = 39322455024

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

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

647 : 1, 647

647 : 1, 647

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 206,456,647,647, is 1.

Now, the common factors can be found like this.

206:2x 103

456:2x 2x 2x 3x 19

647:647

647:647

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

2x 647 = 1294

Therefore, the value for common factors is 1294.

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 = 39322455024/(1x1294)

LCM = 39322455024/1294

LCM = 30388296

Thus, we can understand that the LCM of 206,456,647,647 is 30388296.
