Given numbers are 7645,9820

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

The LCM of 7645,9820 is 15014780.

Find LCM of 7645,9820 with Prime Factorization

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

5 x 1529 x 1964 = 15014780

Therefore, the lowest common multiple of 7645,9820 is 15014780.

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.

7645 x 9820 = 75073900

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.

7645 : 1, 5, 11, 55, 139, 695, 1529, 7645

9820 : 1, 2, 4, 5, 10, 20, 491, 982, 1964, 2455, 4910, 9820

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7645,9820, is 5.

Now, the common factors can be found like this.

7645:5x 11x 139

9820:2x 2x 5x 491

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 = 75073900/(5x1)

LCM = 75073900/5

LCM = 15014780

Thus, we can understand that the LCM of 7645,9820 is 15014780.
