Given numbers are 243,394,607,572,721

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

The LCM of 243,394,607,572,721 is 11983742935164.

Find LCM of 243,394,607,572,721 with Prime Factorization

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

2 x 243 x 197 x 607 x 286 x 721 = 11983742935164

Therefore, the lowest common multiple of 243,394,607,572,721 is 11983742935164.

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 394 x 607 x 572 x 721 = 23967485870328

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

394 : 1, 2, 197, 394

607 : 1, 607

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,394,607,572,721, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

394:2x 197

607:607

572:2x 2x 11x 13

721:7x 103

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

2 = 2

Therefore, the value for common factors is 2.

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 = 23967485870328/(1x2)

LCM = 23967485870328/2

LCM = 11983742935164

Thus, we can understand that the LCM of 243,394,607,572,721 is 11983742935164.
