Calculate the LCM of 398,310,647,294,291

Given numbers are 398,310,647,294,291

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

The LCM of 398,310,647,294,291 is 569125598370.

Find LCM of 398,310,647,294,291 with Prime Factorization


2 398, 310, 647, 294, 291
3 199, 155, 647, 147, 291
199, 155, 647, 49, 97

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

2 x 3 x 199 x 155 x 647 x 49 x 97 = 569125598370

Therefore, the lowest common multiple of 398,310,647,294,291 is 569125598370.

LCM Formula to Find Lowest Common Multiple of 398,310,647,294,291

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.

398 x 310 x 647 x 294 x 291 = 6829507180440

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.

398 : 1, 2, 199, 398

310 : 1, 2, 5, 10, 31, 62, 155, 310

647 : 1, 647

294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294

291 : 1, 3, 97, 291

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,310,647,294,291, is 1.

Now, the common factors can be found like this.

398:2x 199

310:2x 5x 31

647:647

294:2x 3x 7x 7

291:3x 97

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 6829507180440/(1x12)

LCM = 6829507180440/12

LCM = 569125598370

Thus, we can understand that the LCM of 398,310,647,294,291 is 569125598370.
