Calculate the LCM of 816,340,894

Given numbers are 816,340,894

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

The LCM of 816,340,894 is 607920.

Find LCM of 816,340,894 with Prime Factorization


2 816, 340, 894
2 408, 170, 447
3 204, 85, 447
17 68, 85, 149
4, 5, 149

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

2 x 2 x 3 x 17 x 4 x 5 x 149 = 607920

Therefore, the lowest common multiple of 816,340,894 is 607920.

LCM Formula to Find Lowest Common Multiple of 816,340,894

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.

816 x 340 x 894 = 248031360

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.

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

894 : 1, 2, 3, 6, 149, 298, 447, 894

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,340,894, is 2.

Now, the common factors can be found like this.

816:2x 2x 2x 2x 3x 17

340:2x 2x 5x 17

894:2x 3x 149

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 3x 17 = 204

Therefore, the value for common factors is 204.

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 = 248031360/(2x204)

LCM = 248031360/408

LCM = 607920

Thus, we can understand that the LCM of 816,340,894 is 607920.
