Given numbers are 7445,1445

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

The LCM of 7445,1445 is 2151605.

Find LCM of 7445,1445 with Prime Factorization

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

5 x 1489 x 289 = 2151605

Therefore, the lowest common multiple of 7445,1445 is 2151605.

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.

7445 x 1445 = 10758025

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.

7445 : 1, 5, 1489, 7445

1445 : 1, 5, 17, 85, 289, 1445

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7445,1445, is 5.

Now, the common factors can be found like this.

7445:5x 1489

1445:5x 17x 17

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 = 10758025/(5x1)

LCM = 10758025/5

LCM = 2151605

Thus, we can understand that the LCM of 7445,1445 is 2151605.
