Given numbers are 645,444,660,171,485

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

The LCM of 645,444,660,171,485 is 5805781740.

Find LCM of 645,444,660,171,485 with Prime Factorization

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

2 x 2 x 3 x 5 x 43 x 37 x 11 x 57 x 97 = 5805781740

Therefore, the lowest common multiple of 645,444,660,171,485 is 5805781740.

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.

645 x 444 x 660 x 171 x 485 = 15675610698000

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

171 : 1, 3, 9, 19, 57, 171

485 : 1, 5, 97, 485

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,444,660,171,485, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

444:2x 2x 3x 37

660:2x 2x 3x 5x 11

171:3x 3x 19

485:5x 97

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 3x 3x 3x 5x 5 = 2700

Therefore, the value for common factors is 2700.

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 = 15675610698000/(1x2700)

LCM = 15675610698000/2700

LCM = 5805781740

Thus, we can understand that the LCM of 645,444,660,171,485 is 5805781740.
