Calculate the LCM of 622,187,340,168

Given numbers are 622,187,340,168

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

The LCM of 622,187,340,168 is 48851880.

Find LCM of 622,187,340,168 with Prime Factorization


2 622, 187, 340, 168
2 311, 187, 170, 84
17 311, 187, 85, 42
311, 11, 5, 42

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

2 x 2 x 17 x 311 x 11 x 5 x 42 = 48851880

Therefore, the lowest common multiple of 622,187,340,168 is 48851880.

LCM Formula to Find Lowest Common Multiple of 622,187,340,168

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.

622 x 187 x 340 x 168 = 6643855680

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.

622 : 1, 2, 311, 622

187 : 1, 11, 17, 187

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

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,187,340,168, is 1.

Now, the common factors can be found like this.

622:2x 311

187:11x 17

340:2x 2x 5x 17

168:2x 2x 2x 3x 7

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 17 = 136

Therefore, the value for common factors is 136.

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 = 6643855680/(1x136)

LCM = 6643855680/136

LCM = 48851880

Thus, we can understand that the LCM of 622,187,340,168 is 48851880.
