Given numbers are 688,131,687,207,687

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

The LCM of 688,131,687,207,687 is 4272337584.

Find LCM of 688,131,687,207,687 with Prime Factorization

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

3 x 229 x 688 x 131 x 1 x 69 x 1 = 4272337584

Therefore, the lowest common multiple of 688,131,687,207,687 is 4272337584.

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.

688 x 131 x 687 x 207 x 687 = 8805287760624

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

131 : 1, 131

687 : 1, 3, 229, 687

207 : 1, 3, 9, 23, 69, 207

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,131,687,207,687, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

131:131

687:3x 229

207:3x 3x 23

687:3x 229

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

3x 3x 229 = 2061

Therefore, the value for common factors is 2061.

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 = 8805287760624/(1x2061)

LCM = 8805287760624/2061

LCM = 4272337584

Thus, we can understand that the LCM of 688,131,687,207,687 is 4272337584.
