Given numbers are 243,328,556,430

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

The LCM of 243,328,556,430 is 2381954040.

Find LCM of 243,328,556,430 with Prime Factorization

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

2 x 2 x 243 x 82 x 139 x 215 = 2381954040

Therefore, the lowest common multiple of 243,328,556,430 is 2381954040.

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.

243 x 328 x 556 x 430 = 19055632320

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.

243 : 1, 3, 9, 27, 81, 243

328 : 1, 2, 4, 8, 41, 82, 164, 328

556 : 1, 2, 4, 139, 278, 556

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,328,556,430, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

328:2x 2x 2x 41

556:2x 2x 139

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 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 19055632320/(1x8)

LCM = 19055632320/8

LCM = 2381954040

Thus, we can understand that the LCM of 243,328,556,430 is 2381954040.
