Given numbers are 638,396,696,253,395

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

The LCM of 638,396,696,253,395 is 208664280.

Find LCM of 638,396,696,253,395 with Prime Factorization

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

2 x 2 x 3 x 11 x 29 x 1 x 3 x 2 x 23 x 395 = 208664280

Therefore, the lowest common multiple of 638,396,696,253,395 is 208664280.

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.

638 x 396 x 696 x 253 x 395 = 17572871004480

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696

253 : 1, 11, 23, 253

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,396,696,253,395, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

396:2x 2x 3x 3x 11

696:2x 2x 2x 3x 29

253:11x 23

395:5x 79

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 2x 3x 11x 11x 29 = 84216

Therefore, the value for common factors is 84216.

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 = 17572871004480/(1x84216)

LCM = 17572871004480/84216

LCM = 208664280

Thus, we can understand that the LCM of 638,396,696,253,395 is 208664280.
