Given numbers are 1209,8021

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

The LCM of 1209,8021 is 745953.

Find LCM of 1209,8021 with Prime Factorization

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

13 x 93 x 617 = 745953

Therefore, the lowest common multiple of 1209,8021 is 745953.

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 8021 = 9697389

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

8021 : 1, 13, 617, 8021

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1209,8021, is 13.

Now, the common factors can be found like this.

1209:3x 13x 31

8021:13x 617

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 = 9697389/(13x1)

LCM = 9697389/13

LCM = 745953

Thus, we can understand that the LCM of 1209,8021 is 745953.
