Given numbers are 3609,7221

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

The LCM of 3609,7221 is 8686863.

Find LCM of 3609,7221 with Prime Factorization

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

3 x 1203 x 2407 = 8686863

Therefore, the lowest common multiple of 3609,7221 is 8686863.

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.

3609 x 7221 = 26060589

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.

3609 : 1, 3, 9, 401, 1203, 3609

7221 : 1, 3, 29, 83, 87, 249, 2407, 7221

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3609,7221, is 3.

Now, the common factors can be found like this.

3609:3x 3x 401

7221:3x 29x 83

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 = 26060589/(3x1)

LCM = 26060589/3

LCM = 8686863

Thus, we can understand that the LCM of 3609,7221 is 8686863.
