Calculate the LCM of 388,770,418

Given numbers are 388,770,418

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

The LCM of 388,770,418 is 2838220.

Find LCM of 388,770,418 with Prime Factorization


2 388, 770, 418
11 194, 385, 209
194, 35, 19

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

2 x 11 x 194 x 35 x 19 = 2838220

Therefore, the lowest common multiple of 388,770,418 is 2838220.

LCM Formula to Find Lowest Common Multiple of 388,770,418

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 770 x 418 = 124881680

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

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,770,418, is 2.

Now, the common factors can be found like this.

388:2x 2x 97

770:2x 5x 7x 11

418:2x 11x 19

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 = 124881680/(2x22)

LCM = 124881680/44

LCM = 2838220

Thus, we can understand that the LCM of 388,770,418 is 2838220.
