Given numbers are 321,978,734,747

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

The LCM of 321,978,734,747 is 9562865418.

Find LCM of 321,978,734,747 with Prime Factorization

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

2 x 3 x 107 x 163 x 367 x 249 = 9562865418

Therefore, the lowest common multiple of 321,978,734,747 is 9562865418.

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.

321 x 978 x 734 x 747 = 172131577524

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.

321 : 1, 3, 107, 321

978 : 1, 2, 3, 6, 163, 326, 489, 978

734 : 1, 2, 367, 734

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,978,734,747, is 1.

Now, the common factors can be found like this.

321:3x 107

978:2x 3x 163

734:2x 367

747:3x 3x 83

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 172131577524/(1x18)

LCM = 172131577524/18

LCM = 9562865418

Thus, we can understand that the LCM of 321,978,734,747 is 9562865418.
