Given numbers are 321,138,365,798

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

The LCM of 321,138,365,798 is 716815470.

Find LCM of 321,138,365,798 with Prime Factorization

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

2 x 3 x 107 x 23 x 365 x 133 = 716815470

Therefore, the lowest common multiple of 321,138,365,798 is 716815470.

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 138 x 365 x 798 = 12902678460

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

365 : 1, 5, 73, 365

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,138,365,798, is 1.

Now, the common factors can be found like this.

321:3x 107

138:2x 3x 23

365:5x 73

798:2x 3x 7x 19

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 = 12902678460/(1x18)

LCM = 12902678460/18

LCM = 716815470

Thus, we can understand that the LCM of 321,138,365,798 is 716815470.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 180, 600, 269, 829
