Given numbers are 138,781,141,204

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

The LCM of 138,781,141,204 is 172229244.

Find LCM of 138,781,141,204 with Prime Factorization

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

2 x 3 x 23 x 781 x 47 x 34 = 172229244

Therefore, the lowest common multiple of 138,781,141,204 is 172229244.

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 781 x 141 x 204 = 3100126392

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

781 : 1, 11, 71, 781

141 : 1, 3, 47, 141

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,781,141,204, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

781:11x 71

141:3x 47

204:2x 2x 3x 17

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 = 3100126392/(1x18)

LCM = 3100126392/18

LCM = 172229244

Thus, we can understand that the LCM of 138,781,141,204 is 172229244.
