Given numbers are 717,687,177,905

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

The LCM of 717,687,177,905 is 8767085235.

Find LCM of 717,687,177,905 with Prime Factorization

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

3 x 239 x 229 x 59 x 905 = 8767085235

Therefore, the lowest common multiple of 717,687,177,905 is 8767085235.

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.

717 x 687 x 177 x 905 = 78903767115

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.

717 : 1, 3, 239, 717

687 : 1, 3, 229, 687

177 : 1, 3, 59, 177

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,687,177,905, is 1.

Now, the common factors can be found like this.

717:3x 239

687:3x 229

177:3x 59

905:5x 181

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 78903767115/(1x9)

LCM = 78903767115/9

LCM = 8767085235

Thus, we can understand that the LCM of 717,687,177,905 is 8767085235.
