Given numbers are 6945,7445

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

The LCM of 6945,7445 is 10341105.

Find LCM of 6945,7445 with Prime Factorization

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

5 x 1389 x 1489 = 10341105

Therefore, the lowest common multiple of 6945,7445 is 10341105.

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.

6945 x 7445 = 51705525

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.

6945 : 1, 3, 5, 15, 463, 1389, 2315, 6945

7445 : 1, 5, 1489, 7445

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6945,7445, is 5.

Now, the common factors can be found like this.

6945:3x 5x 463

7445:5x 1489

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 = 51705525/(5x1)

LCM = 51705525/5

LCM = 10341105

Thus, we can understand that the LCM of 6945,7445 is 10341105.
