Find LCM of 638,638,499,348,844 with Prime Factorization
| 2 | 638, 638, 499, 348, 844 |
| 2 | 319, 319, 499, 174, 422 |
| 11 | 319, 319, 499, 87, 211 |
| 29 | 29, 29, 499, 87, 211 |
| 1, 1, 499, 3, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 29 x 1 x 1 x 499 x 3 x 211 = 403046292
Therefore, the lowest common multiple of 638,638,499,348,844 is 403046292.
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 638 x 499 x 348 x 844 = 59657299956672
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
638 : 1, 2, 11, 22, 29, 58, 319, 638
499 : 1, 499
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
844 : 1, 2, 4, 211, 422, 844
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,638,499,348,844, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
638:2x 11x 29
499:499
348:2x 2x 3x 29
844:2x 2x 211
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 2x 11x 29x 29 = 148016
Therefore, the value for common factors is 148016.
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 = 59657299956672/(1x148016)
LCM = 59657299956672/148016
LCM = 403046292
Thus, we can understand that the LCM of 638,638,499,348,844 is 403046292.
