Given numbers are 321,363,422,978

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

The LCM of 321,363,422,978 is 2671717026.

Find LCM of 321,363,422,978 with Prime Factorization

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

2 x 3 x 107 x 121 x 211 x 163 = 2671717026

Therefore, the lowest common multiple of 321,363,422,978 is 2671717026.

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 363 x 422 x 978 = 48090906468

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

363 : 1, 3, 11, 33, 121, 363

422 : 1, 2, 211, 422

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,363,422,978, is 1.

Now, the common factors can be found like this.

321:3x 107

363:3x 11x 11

422:2x 211

978:2x 3x 163

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 = 48090906468/(1x18)

LCM = 48090906468/18

LCM = 2671717026

Thus, we can understand that the LCM of 321,363,422,978 is 2671717026.
