Given numbers are 398,927,721,415

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

The LCM of 398,927,721,415 is 1071788130.

Find LCM of 398,927,721,415 with Prime Factorization

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

103 x 398 x 9 x 7 x 415 = 1071788130

Therefore, the lowest common multiple of 398,927,721,415 is 1071788130.

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 927 x 721 x 415 = 110394177390

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

927 : 1, 3, 9, 103, 309, 927

721 : 1, 7, 103, 721

415 : 1, 5, 83, 415

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,927,721,415, is 1.

Now, the common factors can be found like this.

398:2x 199

927:3x 3x 103

721:7x 103

415:5x 83

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

103 = 103

Therefore, the value for common factors is 103.

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 = 110394177390/(1x103)

LCM = 110394177390/103

LCM = 1071788130

Thus, we can understand that the LCM of 398,927,721,415 is 1071788130.
