Calculate the LCM of 388,418,253,191

Given numbers are 388,418,253,191

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

The LCM of 388,418,253,191 is 356237156.

Find LCM of 388,418,253,191 with Prime Factorization


2 388, 418, 253, 191
11 194, 209, 253, 191
194, 19, 23, 191

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

2 x 11 x 194 x 19 x 23 x 191 = 356237156

Therefore, the lowest common multiple of 388,418,253,191 is 356237156.

LCM Formula to Find Lowest Common Multiple of 388,418,253,191

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 418 x 253 x 191 = 7837217432

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

418 : 1, 2, 11, 19, 22, 38, 209, 418

253 : 1, 11, 23, 253

191 : 1, 191

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,418,253,191, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

418:2x 11x 19

253:11x 23

191:191

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 7837217432/(1x22)

LCM = 7837217432/22

LCM = 356237156

Thus, we can understand that the LCM of 388,418,253,191 is 356237156.
