Given numbers are 388,227,428,691

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

The LCM of 388,227,428,691 is 6512075212.

Find LCM of 388,227,428,691 with Prime Factorization

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

2 x 2 x 97 x 227 x 107 x 691 = 6512075212

Therefore, the lowest common multiple of 388,227,428,691 is 6512075212.

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.

388 x 227 x 428 x 691 = 26048300848

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.

388 : 1, 2, 4, 97, 194, 388

227 : 1, 227

428 : 1, 2, 4, 107, 214, 428

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,227,428,691, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

227:227

428:2x 2x 107

691:691

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 26048300848/(1x4)

LCM = 26048300848/4

LCM = 6512075212

Thus, we can understand that the LCM of 388,227,428,691 is 6512075212.
