Given numbers are 422,211,687,838

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

The LCM of 422,211,687,838 is 121473966.

Find LCM of 422,211,687,838 with Prime Factorization

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

2 x 211 x 1 x 1 x 687 x 419 = 121473966

Therefore, the lowest common multiple of 422,211,687,838 is 121473966.

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 211 x 687 x 838 = 51262013652

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

211 : 1, 211

687 : 1, 3, 229, 687

838 : 1, 2, 419, 838

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,211,687,838, is 1.

Now, the common factors can be found like this.

422:2x 211

211:211

687:3x 229

838:2x 419

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

2x 211 = 422

Therefore, the value for common factors is 422.

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 = 51262013652/(1x422)

LCM = 51262013652/422

LCM = 121473966

Thus, we can understand that the LCM of 422,211,687,838 is 121473966.
