Given numbers are 454,40,681

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

The LCM of 454,40,681 is 27240.

Find LCM of 454,40,681 with Prime Factorization

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

2 x 227 x 1 x 20 x 3 = 27240

Therefore, the lowest common multiple of 454,40,681 is 27240.

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.

454 x 40 x 681 = 12366960

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.

454 : 1, 2, 227, 454

40 : 1, 2, 4, 5, 8, 10, 20, 40

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,40,681, is 1.

Now, the common factors can be found like this.

454:2x 227

40:2x 2x 2x 5

681:3x 227

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

2x 227 = 454

Therefore, the value for common factors is 454.

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 = 12366960/(1x454)

LCM = 12366960/454

LCM = 27240

Thus, we can understand that the LCM of 454,40,681 is 27240.
