Given numbers are 138,610,331,69

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

The LCM of 138,610,331,69 is 13931790.

Find LCM of 138,610,331,69 with Prime Factorization

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

2 x 3 x 23 x 1 x 305 x 331 x 1 = 13931790

Therefore, the lowest common multiple of 138,610,331,69 is 13931790.

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 610 x 331 x 69 = 1922587020

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

610 : 1, 2, 5, 10, 61, 122, 305, 610

331 : 1, 331

69 : 1, 3, 23, 69

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,610,331,69, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

610:2x 5x 61

331:331

69:3x 23

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 23 = 138

Therefore, the value for common factors is 138.

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 = 1922587020/(1x138)

LCM = 1922587020/138

LCM = 13931790

Thus, we can understand that the LCM of 138,610,331,69 is 13931790.
