Given numbers are 398,338,266,402

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

The LCM of 398,338,266,402 is 1798115046.

Find LCM of 398,338,266,402 with Prime Factorization

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

2 x 199 x 169 x 133 x 201 = 1798115046

Therefore, the lowest common multiple of 398,338,266,402 is 1798115046.

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.

398 x 338 x 266 x 402 = 14384920368

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.

398 : 1, 2, 199, 398

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

266 : 1, 2, 7, 14, 19, 38, 133, 266

402 : 1, 2, 3, 6, 67, 134, 201, 402

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,338,266,402, is 2.

Now, the common factors can be found like this.

398:2x 199

338:2x 13x 13

266:2x 7x 19

402:2x 3x 67

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 = 14384920368/(2x4)

LCM = 14384920368/8

LCM = 1798115046

Thus, we can understand that the LCM of 398,338,266,402 is 1798115046.
