Given numbers are 398,634,783,712

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

The LCM of 398,634,783,712 is 35168520168.

Find LCM of 398,634,783,712 with Prime Factorization

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

2 x 199 x 317 x 783 x 356 = 35168520168

Therefore, the lowest common multiple of 398,634,783,712 is 35168520168.

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 634 x 783 x 712 = 140674080672

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

634 : 1, 2, 317, 634

783 : 1, 3, 9, 27, 29, 87, 261, 783

712 : 1, 2, 4, 8, 89, 178, 356, 712

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,634,783,712, is 1.

Now, the common factors can be found like this.

398:2x 199

634:2x 317

783:3x 3x 3x 29

712:2x 2x 2x 89

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 = 140674080672/(1x4)

LCM = 140674080672/4

LCM = 35168520168

Thus, we can understand that the LCM of 398,634,783,712 is 35168520168.
