The LCM of 696,638,823,783,989 is 56084204088.
Find LCM of 696,638,823,783,989 with Prime Factorization
| 2 | 696, 638, 823, 783, 989 |
| 3 | 348, 319, 823, 783, 989 |
| 29 | 116, 319, 823, 261, 989 |
| 4, 11, 823, 9, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 4 x 11 x 823 x 9 x 989 = 56084204088
Therefore, the lowest common multiple of 696,638,823,783,989 is 56084204088.
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.
696 x 638 x 823 x 783 x 989 = 283000893828048
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.
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
638 : 1, 2, 11, 22, 29, 58, 319, 638
823 : 1, 823
783 : 1, 3, 9, 27, 29, 87, 261, 783
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 696,638,823,783,989, is 1.
Now, the common factors can be found like this.
696:2x 2x 2x 3x 29
638:2x 11x 29
823:823
783:3x 3x 3x 29
989:23x 43
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 29x 29 = 5046
Therefore, the value for common factors is 5046.
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 = 283000893828048/(1x5046)
LCM = 283000893828048/5046
LCM = 56084204088
Thus, we can understand that the LCM of 696,638,823,783,989 is 56084204088.
