Given numbers are 191,740,138,321

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

The LCM of 191,740,138,321 is 1043513220.

Find LCM of 191,740,138,321 with Prime Factorization

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

2 x 3 x 191 x 370 x 23 x 107 = 1043513220

Therefore, the lowest common multiple of 191,740,138,321 is 1043513220.

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.

191 x 740 x 138 x 321 = 6261079320

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.

191 : 1, 191

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

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

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,740,138,321, is 1.

Now, the common factors can be found like this.

191:191

740:2x 2x 5x 37

138:2x 3x 23

321:3x 107

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 6261079320/(1x6)

LCM = 6261079320/6

LCM = 1043513220

Thus, we can understand that the LCM of 191,740,138,321 is 1043513220.
