Given numbers are 398,332,970,195,721

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

The LCM of 398,332,970,195,721 is 901016554620.

Find LCM of 398,332,970,195,721 with Prime Factorization

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

2 x 5 x 199 x 166 x 97 x 39 x 721 = 901016554620

Therefore, the lowest common multiple of 398,332,970,195,721 is 901016554620.

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 332 x 970 x 195 x 721 = 18020331092400

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

332 : 1, 2, 4, 83, 166, 332

970 : 1, 2, 5, 10, 97, 194, 485, 970

195 : 1, 3, 5, 13, 15, 39, 65, 195

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,332,970,195,721, is 1.

Now, the common factors can be found like this.

398:2x 199

332:2x 2x 83

970:2x 5x 97

195:3x 5x 13

721:7x 103

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 18020331092400/(1x20)

LCM = 18020331092400/20

LCM = 901016554620

Thus, we can understand that the LCM of 398,332,970,195,721 is 901016554620.
