Given numbers are 398,297,753,686

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

The LCM of 398,297,753,686 is 10176709158.

Find LCM of 398,297,753,686 with Prime Factorization

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

2 x 3 x 199 x 99 x 251 x 343 = 10176709158

Therefore, the lowest common multiple of 398,297,753,686 is 10176709158.

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 297 x 753 x 686 = 61060254948

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

297 : 1, 3, 9, 11, 27, 33, 99, 297

753 : 1, 3, 251, 753

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,297,753,686, is 1.

Now, the common factors can be found like this.

398:2x 199

297:3x 3x 3x 11

753:3x 251

686:2x 7x 7x 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 3 = 6

Therefore, the value for common factors is 6.

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 = 61060254948/(1x6)

LCM = 61060254948/6

LCM = 10176709158

Thus, we can understand that the LCM of 398,297,753,686 is 10176709158.
