Given numbers are 397,351,269,747

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

The LCM of 397,351,269,747 is 3111200469.

Find LCM of 397,351,269,747 with Prime Factorization

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

3 x 3 x 397 x 39 x 269 x 83 = 3111200469

Therefore, the lowest common multiple of 397,351,269,747 is 3111200469.

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.

397 x 351 x 269 x 747 = 28000804221

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.

397 : 1, 397

351 : 1, 3, 9, 13, 27, 39, 117, 351

269 : 1, 269

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,351,269,747, is 1.

Now, the common factors can be found like this.

397:397

351:3x 3x 3x 13

269:269

747:3x 3x 83

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 28000804221/(1x9)

LCM = 28000804221/9

LCM = 3111200469

Thus, we can understand that the LCM of 397,351,269,747 is 3111200469.
