Given numbers are 321,442,735,753

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

The LCM of 321,442,735,753 is 8725033590.

Find LCM of 321,442,735,753 with Prime Factorization

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

3 x 107 x 442 x 245 x 251 = 8725033590

Therefore, the lowest common multiple of 321,442,735,753 is 8725033590.

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 442 x 735 x 753 = 78525302310

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

442 : 1, 2, 13, 17, 26, 34, 221, 442

735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735

753 : 1, 3, 251, 753

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,442,735,753, is 1.

Now, the common factors can be found like this.

321:3x 107

442:2x 13x 17

735:3x 5x 7x 7

753:3x 251

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 78525302310/(1x9)

LCM = 78525302310/9

LCM = 8725033590

Thus, we can understand that the LCM of 321,442,735,753 is 8725033590.
