Given numbers are 397,273,427,728

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

The LCM of 397,273,427,728 is 52889928.

Find LCM of 397,273,427,728 with Prime Factorization

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

7 x 13 x 397 x 3 x 61 x 8 = 52889928

Therefore, the lowest common multiple of 397,273,427,728 is 52889928.

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 273 x 427 x 728 = 33690884136

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

273 : 1, 3, 7, 13, 21, 39, 91, 273

427 : 1, 7, 61, 427

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,273,427,728, is 1.

Now, the common factors can be found like this.

397:397

273:3x 7x 13

427:7x 61

728:2x 2x 2x 7x 13

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

7x 7x 13 = 637

Therefore, the value for common factors is 637.

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 = 33690884136/(1x637)

LCM = 33690884136/637

LCM = 52889928

Thus, we can understand that the LCM of 397,273,427,728 is 52889928.
