Given numbers are 1209,8515

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

The LCM of 1209,8515 is 791895.

Find LCM of 1209,8515 with Prime Factorization

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

13 x 93 x 655 = 791895

Therefore, the lowest common multiple of 1209,8515 is 791895.

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.

1209 x 8515 = 10294635

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.

1209 : 1, 3, 13, 31, 39, 93, 403, 1209

8515 : 1, 5, 13, 65, 131, 655, 1703, 8515

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1209,8515, is 13.

Now, the common factors can be found like this.

1209:3x 13x 31

8515:5x 13x 131

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 = 10294635/(13x1)

LCM = 10294635/13

LCM = 791895

Thus, we can understand that the LCM of 1209,8515 is 791895.
