Given numbers are 138,381,906,449

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

The LCM of 138,381,906,449 is 1188245274.

Find LCM of 138,381,906,449 with Prime Factorization

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

2 x 3 x 23 x 127 x 151 x 449 = 1188245274

Therefore, the lowest common multiple of 138,381,906,449 is 1188245274.

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.

138 x 381 x 906 x 449 = 21388414932

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.

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

381 : 1, 3, 127, 381

906 : 1, 2, 3, 6, 151, 302, 453, 906

449 : 1, 449

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,381,906,449, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

381:3x 127

906:2x 3x 151

449:449

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 21388414932/(1x18)

LCM = 21388414932/18

LCM = 1188245274

Thus, we can understand that the LCM of 138,381,906,449 is 1188245274.
