Given numbers are 889,720,422,69

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

The LCM of 889,720,422,69 is 3106308240.

Find LCM of 889,720,422,69 with Prime Factorization

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

2 x 3 x 889 x 120 x 211 x 23 = 3106308240

Therefore, the lowest common multiple of 889,720,422,69 is 3106308240.

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.

889 x 720 x 422 x 69 = 18637849440

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.

889 : 1, 7, 127, 889

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

422 : 1, 2, 211, 422

69 : 1, 3, 23, 69

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,720,422,69, is 1.

Now, the common factors can be found like this.

889:7x 127

720:2x 2x 2x 2x 3x 3x 5

422:2x 211

69:3x 23

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 18637849440/(1x6)

LCM = 18637849440/6

LCM = 3106308240

Thus, we can understand that the LCM of 889,720,422,69 is 3106308240.
