Given numbers are 422,121,138,954

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

The LCM of 422,121,138,954 is 560201202.

Find LCM of 422,121,138,954 with Prime Factorization

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

2 x 3 x 211 x 121 x 23 x 159 = 560201202

Therefore, the lowest common multiple of 422,121,138,954 is 560201202.

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 121 x 138 x 954 = 6722414424

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

121 : 1, 11, 121

138 : 1, 2, 3, 6, 23, 46, 69, 138

954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,121,138,954, is 1.

Now, the common factors can be found like this.

422:2x 211

121:11x 11

138:2x 3x 23

954:2x 3x 3x 53

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 3 = 12

Therefore, the value for common factors is 12.

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 = 6722414424/(1x12)

LCM = 6722414424/12

LCM = 560201202

Thus, we can understand that the LCM of 422,121,138,954 is 560201202.
