Given numbers are 422,218,186,620

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

The LCM of 422,218,186,620 is 42778140.

Find LCM of 422,218,186,620 with Prime Factorization

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

2 x 31 x 211 x 109 x 3 x 10 = 42778140

Therefore, the lowest common multiple of 422,218,186,620 is 42778140.

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 218 x 186 x 620 = 10608978720

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

218 : 1, 2, 109, 218

186 : 1, 2, 3, 6, 31, 62, 93, 186

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,218,186,620, is 2.

Now, the common factors can be found like this.

422:2x 211

218:2x 109

186:2x 3x 31

620:2x 2x 5x 31

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 31 = 124

Therefore, the value for common factors is 124.

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 = 10608978720/(2x124)

LCM = 10608978720/248

LCM = 42778140

Thus, we can understand that the LCM of 422,218,186,620 is 42778140.
