Given numbers are 404,194,210,398

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

The LCM of 404,194,210,398 is 818833260.

Find LCM of 404,194,210,398 with Prime Factorization

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

2 x 202 x 97 x 105 x 199 = 818833260

Therefore, the lowest common multiple of 404,194,210,398 is 818833260.

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 194 x 210 x 398 = 6550666080

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

194 : 1, 2, 97, 194

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

398 : 1, 2, 199, 398

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 404,194,210,398, is 2.

Now, the common factors can be found like this.

404:2x 2x 101

194:2x 97

210:2x 3x 5x 7

398:2x 199

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 = 6550666080/(2x4)

LCM = 6550666080/8

LCM = 818833260

Thus, we can understand that the LCM of 404,194,210,398 is 818833260.
