Given numbers are 398,554,412,721

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

The LCM of 398,554,412,721 is 158974732.

Find LCM of 398,554,412,721 with Prime Factorization

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

2 x 103 x 199 x 277 x 2 x 7 = 158974732

Therefore, the lowest common multiple of 398,554,412,721 is 158974732.

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 554 x 412 x 721 = 65497589584

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

554 : 1, 2, 277, 554

412 : 1, 2, 4, 103, 206, 412

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,554,412,721, is 1.

Now, the common factors can be found like this.

398:2x 199

554:2x 277

412:2x 2x 103

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 103 = 412

Therefore, the value for common factors is 412.

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 = 65497589584/(1x412)

LCM = 65497589584/412

LCM = 158974732

Thus, we can understand that the LCM of 398,554,412,721 is 158974732.
