Given numbers are 205,740,655,430

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

The LCM of 205,740,655,430 is 170905220.

Find LCM of 205,740,655,430 with Prime Factorization

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

2 x 5 x 41 x 74 x 131 x 43 = 170905220

Therefore, the lowest common multiple of 205,740,655,430 is 170905220.

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.

205 x 740 x 655 x 430 = 42726305000

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.

205 : 1, 5, 41, 205

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

655 : 1, 5, 131, 655

430 : 1, 2, 5, 10, 43, 86, 215, 430

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,740,655,430, is 5.

Now, the common factors can be found like this.

205:5x 41

740:2x 2x 5x 37

655:5x 131

430:2x 5x 43

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

2x 5x 5 = 50

Therefore, the value for common factors is 50.

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 = 42726305000/(5x50)

LCM = 42726305000/250

LCM = 170905220

Thus, we can understand that the LCM of 205,740,655,430 is 170905220.
