Given numbers are 398,517,722,285,398

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

The LCM of 398,517,722,285,398 is 1114222890.

Find LCM of 398,517,722,285,398 with Prime Factorization

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

2 x 19 x 199 x 1 x 517 x 19 x 15 x 1 = 1114222890

Therefore, the lowest common multiple of 398,517,722,285,398 is 1114222890.

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 517 x 722 x 285 x 398 = 16851506988360

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

517 : 1, 11, 47, 517

722 : 1, 2, 19, 38, 361, 722

285 : 1, 3, 5, 15, 19, 57, 95, 285

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,517,722,285,398, is 1.

Now, the common factors can be found like this.

398:2x 199

517:11x 47

722:2x 19x 19

285:3x 5x 19

398:2x 199

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 19x 199 = 15124

Therefore, the value for common factors is 15124.

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 = 16851506988360/(1x15124)

LCM = 16851506988360/15124

LCM = 1114222890

Thus, we can understand that the LCM of 398,517,722,285,398 is 1114222890.
