Given numbers are 388,157,921,388

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

The LCM of 388,157,921,388 is 56103636.

Find LCM of 388,157,921,388 with Prime Factorization

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

2 x 2 x 97 x 1 x 157 x 921 x 1 = 56103636

Therefore, the lowest common multiple of 388,157,921,388 is 56103636.

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 157 x 921 x 388 = 21768210768

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

157 : 1, 157

921 : 1, 3, 307, 921

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,157,921,388, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

157:157

921:3x 307

388:2x 2x 97

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 97 = 388

Therefore, the value for common factors is 388.

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 = 21768210768/(1x388)

LCM = 21768210768/388

LCM = 56103636

Thus, we can understand that the LCM of 388,157,921,388 is 56103636.
