Find LCM of 696,279,821,783,809 with Prime Factorization
| 3 | 696, 279, 821, 783, 809 |
| 3 | 232, 93, 821, 261, 809 |
| 29 | 232, 31, 821, 87, 809 |
| 8, 31, 821, 3, 809 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 29 x 8 x 31 x 821 x 3 x 809 = 128974876776
Therefore, the lowest common multiple of 696,279,821,783,809 is 128974876776.
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 279 x 821 x 783 x 809 = 100987328515608
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
279 : 1, 3, 9, 31, 93, 279
821 : 1, 821
783 : 1, 3, 9, 27, 29, 87, 261, 783
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 696,279,821,783,809, is 1.
Now, the common factors can be found like this.
696:2x 2x 2x 3x 29
279:3x 3x 31
821:821
783:3x 3x 3x 29
809:809
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 29 = 783
Therefore, the value for common factors is 783.
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 = 100987328515608/(1x783)
LCM = 100987328515608/783
LCM = 128974876776
Thus, we can understand that the LCM of 696,279,821,783,809 is 128974876776.
