Given numbers are 561,194,458,315

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

The LCM of 561,194,458,315 is 2616913530.

Find LCM of 561,194,458,315 with Prime Factorization

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

2 x 3 x 187 x 97 x 229 x 105 = 2616913530

Therefore, the lowest common multiple of 561,194,458,315 is 2616913530.

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.

561 x 194 x 458 x 315 = 15701481180

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.

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

194 : 1, 2, 97, 194

458 : 1, 2, 229, 458

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,194,458,315, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

194:2x 97

458:2x 229

315:3x 3x 5x 7

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 = 15701481180/(1x6)

LCM = 15701481180/6

LCM = 2616913530

Thus, we can understand that the LCM of 561,194,458,315 is 2616913530.
