Given numbers are 398,598,764,454,621

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

The LCM of 398,598,764,454,621 is 278616764556.

Find LCM of 398,598,764,454,621 with Prime Factorization

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

2 x 23 x 199 x 13 x 382 x 227 x 27 = 278616764556

Therefore, the lowest common multiple of 398,598,764,454,621 is 278616764556.

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 598 x 764 x 454 x 621 = 51265484678304

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

598 : 1, 2, 13, 23, 26, 46, 299, 598

764 : 1, 2, 4, 191, 382, 764

454 : 1, 2, 227, 454

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,598,764,454,621, is 1.

Now, the common factors can be found like this.

398:2x 199

598:2x 13x 23

764:2x 2x 191

454:2x 227

621:3x 3x 3x 23

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 2x 23 = 184

Therefore, the value for common factors is 184.

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 = 51265484678304/(1x184)

LCM = 51265484678304/184

LCM = 278616764556

Thus, we can understand that the LCM of 398,598,764,454,621 is 278616764556.
