Given numbers are 404,338,538,690

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

The LCM of 404,338,538,690 is 6336354180.

Find LCM of 404,338,538,690 with Prime Factorization

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

2 x 202 x 169 x 269 x 345 = 6336354180

Therefore, the lowest common multiple of 404,338,538,690 is 6336354180.

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.

404 x 338 x 538 x 690 = 50690833440

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.

404 : 1, 2, 4, 101, 202, 404

338 : 1, 2, 13, 26, 169, 338

538 : 1, 2, 269, 538

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 404,338,538,690, is 2.

Now, the common factors can be found like this.

404:2x 2x 101

338:2x 13x 13

538:2x 269

690:2x 3x 5x 23

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 50690833440/(2x4)

LCM = 50690833440/8

LCM = 6336354180

Thus, we can understand that the LCM of 404,338,538,690 is 6336354180.
