Given numbers are 646,106,969,257

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

The LCM of 646,106,969,257 is 26397498.

Find LCM of 646,106,969,257 with Prime Factorization

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

2 x 17 x 19 x 1 x 53 x 3 x 257 = 26397498

Therefore, the lowest common multiple of 646,106,969,257 is 26397498.

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 106 x 969 x 257 = 17052783708

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

106 : 1, 2, 53, 106

969 : 1, 3, 17, 19, 51, 57, 323, 969

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,106,969,257, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

106:2x 53

969:3x 17x 19

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 17x 19 = 646

Therefore, the value for common factors is 646.

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 = 17052783708/(1x646)

LCM = 17052783708/646

LCM = 26397498

Thus, we can understand that the LCM of 646,106,969,257 is 26397498.
