Calculate the LCM of 731,394,643,433,452

Given numbers are 731,394,643,433,452

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

The LCM of 731,394,643,433,452 is 18122616789716.

Find LCM of 731,394,643,433,452 with Prime Factorization


2 731, 394, 643, 433, 452
731, 197, 643, 433, 226

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

2 x 731 x 197 x 643 x 433 x 226 = 18122616789716

Therefore, the lowest common multiple of 731,394,643,433,452 is 18122616789716.

LCM Formula to Find Lowest Common Multiple of 731,394,643,433,452

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.

731 x 394 x 643 x 433 x 452 = 36245233579432

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.

731 : 1, 17, 43, 731

394 : 1, 2, 197, 394

643 : 1, 643

433 : 1, 433

452 : 1, 2, 4, 113, 226, 452

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,394,643,433,452, is 1.

Now, the common factors can be found like this.

731:17x 43

394:2x 197

643:643

433:433

452:2x 2x 113

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 = 36245233579432/(1x2)

LCM = 36245233579432/2

LCM = 18122616789716

Thus, we can understand that the LCM of 731,394,643,433,452 is 18122616789716.
