Given numbers are 243,695,556,457

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

The LCM of 243,695,556,457 is 308721780.

Find LCM of 243,695,556,457 with Prime Factorization

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

139 x 243 x 5 x 4 x 457 = 308721780

Therefore, the lowest common multiple of 243,695,556,457 is 308721780.

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 695 x 556 x 457 = 42912327420

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

695 : 1, 5, 139, 695

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

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,695,556,457, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

695:5x 139

556:2x 2x 139

457:457

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

139 = 139

Therefore, the value for common factors is 139.

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 = 42912327420/(1x139)

LCM = 42912327420/139

LCM = 308721780

Thus, we can understand that the LCM of 243,695,556,457 is 308721780.
