Calculate the LCM of 397,305,465,939

Given numbers are 397,305,465,939

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

The LCM of 397,305,465,939 is 3524663265.

Find LCM of 397,305,465,939 with Prime Factorization


3 397, 305, 465, 939
5 397, 305, 155, 313
397, 61, 31, 313

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

3 x 5 x 397 x 61 x 31 x 313 = 3524663265

Therefore, the lowest common multiple of 397,305,465,939 is 3524663265.

LCM Formula to Find Lowest Common Multiple of 397,305,465,939

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 305 x 465 x 939 = 52869948975

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

305 : 1, 5, 61, 305

465 : 1, 3, 5, 15, 31, 93, 155, 465

939 : 1, 3, 313, 939

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,305,465,939, is 1.

Now, the common factors can be found like this.

397:397

305:5x 61

465:3x 5x 31

939:3x 313

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 52869948975/(1x15)

LCM = 52869948975/15

LCM = 3524663265

Thus, we can understand that the LCM of 397,305,465,939 is 3524663265.
