Given numbers are 1645,5505

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

The LCM of 1645,5505 is 1811145.

Find LCM of 1645,5505 with Prime Factorization

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

5 x 329 x 1101 = 1811145

Therefore, the lowest common multiple of 1645,5505 is 1811145.

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.

1645 x 5505 = 9055725

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.

1645 : 1, 5, 7, 35, 47, 235, 329, 1645

5505 : 1, 3, 5, 15, 367, 1101, 1835, 5505

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1645,5505, is 5.

Now, the common factors can be found like this.

1645:5x 7x 47

5505:3x 5x 367

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 = 9055725/(5x1)

LCM = 9055725/5

LCM = 1811145

Thus, we can understand that the LCM of 1645,5505 is 1811145.
