Calculate the LCM of 397,820,442,394,419

Given numbers are 397,820,442,394,419

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

The LCM of 397,820,442,394,419 is 5938501656620.

Find LCM of 397,820,442,394,419 with Prime Factorization


2 397, 820, 442, 394, 419
397, 410, 221, 197, 419

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

2 x 397 x 410 x 221 x 197 x 419 = 5938501656620

Therefore, the lowest common multiple of 397,820,442,394,419 is 5938501656620.

LCM Formula to Find Lowest Common Multiple of 397,820,442,394,419

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 820 x 442 x 394 x 419 = 23754006626480

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

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

442 : 1, 2, 13, 17, 26, 34, 221, 442

394 : 1, 2, 197, 394

419 : 1, 419

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,820,442,394,419, is 1.

Now, the common factors can be found like this.

397:397

820:2x 2x 5x 41

442:2x 13x 17

394:2x 197

419:419

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 23754006626480/(1x4)

LCM = 23754006626480/4

LCM = 5938501656620

Thus, we can understand that the LCM of 397,820,442,394,419 is 5938501656620.
