Given numbers are 646,632,206,257

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

The LCM of 646,632,206,257 is 5403684056.

Find LCM of 646,632,206,257 with Prime Factorization

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

2 x 323 x 316 x 103 x 257 = 5403684056

Therefore, the lowest common multiple of 646,632,206,257 is 5403684056.

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.

646 x 632 x 206 x 257 = 21614736224

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

632 : 1, 2, 4, 8, 79, 158, 316, 632

206 : 1, 2, 103, 206

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,632,206,257, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

632:2x 2x 2x 79

206:2x 103

257:257

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 = 21614736224/(1x4)

LCM = 21614736224/4

LCM = 5403684056

Thus, we can understand that the LCM of 646,632,206,257 is 5403684056.
