Given numbers are 815,682,102,289

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

The LCM of 815,682,102,289 is 481904610.

Find LCM of 815,682,102,289 with Prime Factorization

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

2 x 17 x 815 x 341 x 3 x 17 = 481904610

Therefore, the lowest common multiple of 815,682,102,289 is 481904610.

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.

815 x 682 x 102 x 289 = 16384756740

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.

815 : 1, 5, 163, 815

682 : 1, 2, 11, 22, 31, 62, 341, 682

102 : 1, 2, 3, 6, 17, 34, 51, 102

289 : 1, 17, 289

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,682,102,289, is 1.

Now, the common factors can be found like this.

815:5x 163

682:2x 11x 31

102:2x 3x 17

289:17x 17

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 16384756740/(1x34)

LCM = 16384756740/34

LCM = 481904610

Thus, we can understand that the LCM of 815,682,102,289 is 481904610.
