Given numbers are 538,454,138,381

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

The LCM of 538,454,138,381 is 1070190138.

Find LCM of 538,454,138,381 with Prime Factorization

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

2 x 3 x 269 x 227 x 23 x 127 = 1070190138

Therefore, the lowest common multiple of 538,454,138,381 is 1070190138.

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.

538 x 454 x 138 x 381 = 12842281656

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.

538 : 1, 2, 269, 538

454 : 1, 2, 227, 454

138 : 1, 2, 3, 6, 23, 46, 69, 138

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,454,138,381, is 1.

Now, the common factors can be found like this.

538:2x 269

454:2x 227

138:2x 3x 23

381:3x 127

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 12842281656/(1x12)

LCM = 12842281656/12

LCM = 1070190138

Thus, we can understand that the LCM of 538,454,138,381 is 1070190138.
