Given numbers are 398,461,905,181

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

The LCM of 398,461,905,181 is 166047590.

Find LCM of 398,461,905,181 with Prime Factorization

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

181 x 398 x 461 x 5 x 1 = 166047590

Therefore, the lowest common multiple of 398,461,905,181 is 166047590.

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 461 x 905 x 181 = 30054613790

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

461 : 1, 461

905 : 1, 5, 181, 905

181 : 1, 181

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,461,905,181, is 1.

Now, the common factors can be found like this.

398:2x 199

461:461

905:5x 181

181:181

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

181 = 181

Therefore, the value for common factors is 181.

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 = 30054613790/(1x181)

LCM = 30054613790/181

LCM = 166047590

Thus, we can understand that the LCM of 398,461,905,181 is 166047590.
