Given numbers are 8705,8170

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

The LCM of 8705,8170 is 14223970.

Find LCM of 8705,8170 with Prime Factorization

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

5 x 1741 x 1634 = 14223970

Therefore, the lowest common multiple of 8705,8170 is 14223970.

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.

8705 x 8170 = 71119850

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.

8705 : 1, 5, 1741, 8705

8170 : 1, 2, 5, 10, 19, 38, 43, 86, 95, 190, 215, 430, 817, 1634, 4085, 8170

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8705,8170, is 5.

Now, the common factors can be found like this.

8705:5x 1741

8170:2x 5x 19x 43

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

= 1

Therefore, the value for common factors is 1.

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 = 71119850/(5x1)

LCM = 71119850/5

LCM = 14223970

Thus, we can understand that the LCM of 8705,8170 is 14223970.
