Calculate the LCM of 988,866,380,736

Given numbers are 988,866,380,736

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

The LCM of 988,866,380,736 is 393579680.

Find LCM of 988,866,380,736 with Prime Factorization


2 988, 866, 380, 736
2 494, 433, 190, 368
19 247, 433, 95, 184
13, 433, 5, 184

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

2 x 2 x 19 x 13 x 433 x 5 x 184 = 393579680

Therefore, the lowest common multiple of 988,866,380,736 is 393579680.

LCM Formula to Find Lowest Common Multiple of 988,866,380,736

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.

988 x 866 x 380 x 736 = 239296445440

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.

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

866 : 1, 2, 433, 866

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,866,380,736, is 2.

Now, the common factors can be found like this.

988:2x 2x 13x 19

866:2x 433

380:2x 2x 5x 19

736:2x 2x 2x 2x 2x 23

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 2x 2x 19 = 304

Therefore, the value for common factors is 304.

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 = 239296445440/(2x304)

LCM = 239296445440/608

LCM = 393579680

Thus, we can understand that the LCM of 988,866,380,736 is 393579680.
