Find LCM of 638,797,676,396,837 with Prime Factorization
| 2 | 638, 797, 676, 396, 837 |
| 2 | 319, 797, 338, 198, 837 |
| 3 | 319, 797, 169, 99, 837 |
| 3 | 319, 797, 169, 33, 279 |
| 11 | 319, 797, 169, 11, 93 |
| 29, 797, 169, 1, 93 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 29 x 797 x 169 x 1 x 93 = 143853740316
Therefore, the lowest common multiple of 638,797,676,396,837 is 143853740316.
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 797 x 676 x 396 x 837 = 113932162330272
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
797 : 1, 797
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
837 : 1, 3, 9, 27, 31, 93, 279, 837
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,797,676,396,837, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
797:797
676:2x 2x 13x 13
396:2x 2x 3x 3x 11
837:3x 3x 3x 31
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 3x 11 = 792
Therefore, the value for common factors is 792.
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 = 113932162330272/(1x792)
LCM = 113932162330272/792
LCM = 143853740316
Thus, we can understand that the LCM of 638,797,676,396,837 is 143853740316.
