Given numbers are 122,427,945,857

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

The LCM of 122,427,945,857 is 98803530.

Find LCM of 122,427,945,857 with Prime Factorization

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

7 x 61 x 2 x 1 x 135 x 857 = 98803530

Therefore, the lowest common multiple of 122,427,945,857 is 98803530.

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.

122 x 427 x 945 x 857 = 42189107310

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.

122 : 1, 2, 61, 122

427 : 1, 7, 61, 427

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,427,945,857, is 1.

Now, the common factors can be found like this.

122:2x 61

427:7x 61

945:3x 3x 3x 5x 7

857:857

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

7x 61 = 427

Therefore, the value for common factors is 427.

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 = 42189107310/(1x427)

LCM = 42189107310/427

LCM = 98803530

Thus, we can understand that the LCM of 122,427,945,857 is 98803530.
