Given numbers are 393,691,988,178

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

The LCM of 393,691,988,178 is 23879077716.

Find LCM of 393,691,988,178 with Prime Factorization

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

2 x 393 x 691 x 494 x 89 = 23879077716

Therefore, the lowest common multiple of 393,691,988,178 is 23879077716.

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.

393 x 691 x 988 x 178 = 47758155432

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.

393 : 1, 3, 131, 393

691 : 1, 691

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

178 : 1, 2, 89, 178

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,691,988,178, is 1.

Now, the common factors can be found like this.

393:3x 131

691:691

988:2x 2x 13x 19

178:2x 89

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 47758155432/(1x2)

LCM = 47758155432/2

LCM = 23879077716

Thus, we can understand that the LCM of 393,691,988,178 is 23879077716.
