Given numbers are 422,214,137,621

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

The LCM of 422,214,137,621 is 3841566858.

Find LCM of 422,214,137,621 with Prime Factorization

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

2 x 211 x 107 x 137 x 621 = 3841566858

Therefore, the lowest common multiple of 422,214,137,621 is 3841566858.

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.

422 x 214 x 137 x 621 = 7683133716

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.

422 : 1, 2, 211, 422

214 : 1, 2, 107, 214

137 : 1, 137

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,214,137,621, is 1.

Now, the common factors can be found like this.

422:2x 211

214:2x 107

137:137

621:3x 3x 3x 23

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 = 7683133716/(1x2)

LCM = 7683133716/2

LCM = 3841566858

Thus, we can understand that the LCM of 422,214,137,621 is 3841566858.

Here are some samples of LCM of two or more Numbers calculations.
