Calculate the LCM of 816,622,689

Given numbers are 816,622,689

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

The LCM of 816,622,689 is 174851664.

Find LCM of 816,622,689 with Prime Factorization


2 816, 622, 689
408, 311, 689

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

2 x 408 x 311 x 689 = 174851664

Therefore, the lowest common multiple of 816,622,689 is 174851664.

LCM Formula to Find Lowest Common Multiple of 816,622,689

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 622 x 689 = 349703328

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

622 : 1, 2, 311, 622

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,622,689, is 1.

Now, the common factors can be found like this.

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

622:2x 311

689:13x 53

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 349703328/(1x2)

LCM = 349703328/2

LCM = 174851664

Thus, we can understand that the LCM of 816,622,689 is 174851664.
