Given numbers are 398,447,698,126

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

The LCM of 398,447,698,126 is 1303873074.

Find LCM of 398,447,698,126 with Prime Factorization

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

2 x 3 x 199 x 149 x 349 x 21 = 1303873074

Therefore, the lowest common multiple of 398,447,698,126 is 1303873074.

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 447 x 698 x 126 = 15646476888

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

447 : 1, 3, 149, 447

698 : 1, 2, 349, 698

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,447,698,126, is 1.

Now, the common factors can be found like this.

398:2x 199

447:3x 149

698:2x 349

126:2x 3x 3x 7

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 3 = 12

Therefore, the value for common factors is 12.

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 = 15646476888/(1x12)

LCM = 15646476888/12

LCM = 1303873074

Thus, we can understand that the LCM of 398,447,698,126 is 1303873074.
