Given numbers are 158,561,121,451

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

The LCM of 158,561,121,451 is 39975738.

Find LCM of 158,561,121,451 with Prime Factorization

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

11 x 158 x 51 x 11 x 41 = 39975738

Therefore, the lowest common multiple of 158,561,121,451 is 39975738.

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.

158 x 561 x 121 x 451 = 4837064298

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.

158 : 1, 2, 79, 158

561 : 1, 3, 11, 17, 33, 51, 187, 561

121 : 1, 11, 121

451 : 1, 11, 41, 451

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,561,121,451, is 1.

Now, the common factors can be found like this.

158:2x 79

561:3x 11x 17

121:11x 11

451:11x 41

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 4837064298/(1x121)

LCM = 4837064298/121

LCM = 39975738

Thus, we can understand that the LCM of 158,561,121,451 is 39975738.
