Find LCM of 798,813,638,551 with Prime Factorization
| 2 | 798, 813, 638, 551 |
| 3 | 399, 813, 319, 551 |
| 19 | 133, 271, 319, 551 |
| 29 | 7, 271, 319, 29 |
| 7, 271, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 29 x 7 x 271 x 11 x 1 = 68986302
Therefore, the lowest common multiple of 798,813,638,551 is 68986302.
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.
798 x 813 x 638 x 551 = 228068714412
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
813 : 1, 3, 271, 813
638 : 1, 2, 11, 22, 29, 58, 319, 638
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,813,638,551, is 1.
Now, the common factors can be found like this.
798:2x 3x 7x 19
813:3x 271
638:2x 11x 29
551:19x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19x 29 = 3306
Therefore, the value for common factors is 3306.
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 = 228068714412/(1x3306)
LCM = 228068714412/3306
LCM = 68986302
Thus, we can understand that the LCM of 798,813,638,551 is 68986302.
