Calculate the LCM of 382,836,400,742

Given numbers are 382,836,400,742

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

The LCM of 382,836,400,742 is 5923979600.

Find LCM of 382,836,400,742 with Prime Factorization


2 382, 836, 400, 742
2 191, 418, 200, 371
191, 209, 100, 371

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

2 x 2 x 191 x 209 x 100 x 371 = 5923979600

Therefore, the lowest common multiple of 382,836,400,742 is 5923979600.

LCM Formula to Find Lowest Common Multiple of 382,836,400,742

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.

382 x 836 x 400 x 742 = 94783673600

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.

382 : 1, 2, 191, 382

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

742 : 1, 2, 7, 14, 53, 106, 371, 742

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,836,400,742, is 2.

Now, the common factors can be found like this.

382:2x 191

836:2x 2x 11x 19

400:2x 2x 2x 2x 5x 5

742:2x 7x 53

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 2 = 8

Therefore, the value for common factors is 8.

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 = 94783673600/(2x8)

LCM = 94783673600/16

LCM = 5923979600

Thus, we can understand that the LCM of 382,836,400,742 is 5923979600.
