Calculate the LCM of 622,676,221,136

Given numbers are 622,676,221,136

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

The LCM of 622,676,221,136 is 7148024.

Find LCM of 622,676,221,136 with Prime Factorization


2 622, 676, 221, 136
2 311, 338, 221, 68
13 311, 169, 221, 34
17 311, 13, 17, 34
311, 13, 1, 2

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

2 x 2 x 13 x 17 x 311 x 13 x 1 x 2 = 7148024

Therefore, the lowest common multiple of 622,676,221,136 is 7148024.

LCM Formula to Find Lowest Common Multiple of 622,676,221,136

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 676 x 221 x 136 = 12637706432

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

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

221 : 1, 13, 17, 221

136 : 1, 2, 4, 8, 17, 34, 68, 136

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,676,221,136, is 1.

Now, the common factors can be found like this.

622:2x 311

676:2x 2x 13x 13

221:13x 17

136:2x 2x 2x 17

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 13x 17 = 1768

Therefore, the value for common factors is 1768.

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 = 12637706432/(1x1768)

LCM = 12637706432/1768

LCM = 7148024

Thus, we can understand that the LCM of 622,676,221,136 is 7148024.
