Calculate the LCM of 331,662,100,378,556

Given numbers are 331,662,100,378,556

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

The LCM of 331,662,100,378,556 is 869570100.

Find LCM of 331,662,100,378,556 with Prime Factorization


2 331, 662, 100, 378, 556
2 331, 331, 50, 189, 278
331 331, 331, 25, 189, 139
1, 1, 25, 189, 139

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

2 x 2 x 331 x 1 x 1 x 25 x 189 x 139 = 869570100

Therefore, the lowest common multiple of 331,662,100,378,556 is 869570100.

LCM Formula to Find Lowest Common Multiple of 331,662,100,378,556

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.

331 x 662 x 100 x 378 x 556 = 4605243249600

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.

331 : 1, 331

662 : 1, 2, 331, 662

100 : 1, 2, 4, 5, 10, 20, 25, 50, 100

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

556 : 1, 2, 4, 139, 278, 556

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,662,100,378,556, is 1.

Now, the common factors can be found like this.

331:331

662:2x 331

100:2x 2x 5x 5

378:2x 3x 3x 3x 7

556:2x 2x 139

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 331 = 5296

Therefore, the value for common factors is 5296.

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 = 4605243249600/(1x5296)

LCM = 4605243249600/5296

LCM = 869570100

Thus, we can understand that the LCM of 331,662,100,378,556 is 869570100.
