Given numbers are 281,439,878,438

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

The LCM of 281,439,878,438 is 54031242.

Find LCM of 281,439,878,438 with Prime Factorization

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

2 x 439 x 281 x 1 x 1 x 219 = 54031242

Therefore, the lowest common multiple of 281,439,878,438 is 54031242.

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.

281 x 439 x 878 x 438 = 47439430476

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.

281 : 1, 281

439 : 1, 439

878 : 1, 2, 439, 878

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,439,878,438, is 1.

Now, the common factors can be found like this.

281:281

439:439

878:2x 439

438:2x 3x 73

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

2x 439 = 878

Therefore, the value for common factors is 878.

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 = 47439430476/(1x878)

LCM = 47439430476/878

LCM = 54031242

Thus, we can understand that the LCM of 281,439,878,438 is 54031242.
