Given numbers are 7485,2105

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

The LCM of 7485,2105 is 3151185.

Find LCM of 7485,2105 with Prime Factorization

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

5 x 1497 x 421 = 3151185

Therefore, the lowest common multiple of 7485,2105 is 3151185.

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.

7485 x 2105 = 15755925

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.

7485 : 1, 3, 5, 15, 499, 1497, 2495, 7485

2105 : 1, 5, 421, 2105

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7485,2105, is 5.

Now, the common factors can be found like this.

7485:3x 5x 499

2105:5x 421

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 = 15755925/(5x1)

LCM = 15755925/5

LCM = 3151185

Thus, we can understand that the LCM of 7485,2105 is 3151185.
