Given numbers are 461,57,285

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

The LCM of 461,57,285 is 131385.

Find LCM of 461,57,285 with Prime Factorization

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

3 x 19 x 461 x 1 x 5 = 131385

Therefore, the lowest common multiple of 461,57,285 is 131385.

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.

461 x 57 x 285 = 7488945

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.

461 : 1, 461

57 : 1, 3, 19, 57

285 : 1, 3, 5, 15, 19, 57, 95, 285

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 461,57,285, is 1.

Now, the common factors can be found like this.

461:461

57:3x 19

285:3x 5x 19

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

3x 19 = 57

Therefore, the value for common factors is 57.

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 = 7488945/(1x57)

LCM = 7488945/57

LCM = 131385

Thus, we can understand that the LCM of 461,57,285 is 131385.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 532, 54, 668
