Given numbers are 40,281,442

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

The LCM of 40,281,442 is 2484040.

Find LCM of 40,281,442 with Prime Factorization

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

2 x 20 x 281 x 221 = 2484040

Therefore, the lowest common multiple of 40,281,442 is 2484040.

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.

40 x 281 x 442 = 4968080

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.

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

281 : 1, 281

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 40,281,442, is 1.

Now, the common factors can be found like this.

40:2x 2x 2x 5

281:281

442:2x 13x 17

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

2 = 2

Therefore, the value for common factors is 2.

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 = 4968080/(1x2)

LCM = 4968080/2

LCM = 2484040

Thus, we can understand that the LCM of 40,281,442 is 2484040.
