Find LCM of 705,880,904,340,867 with Prime Factorization
| 2 | 705, 880, 904, 340, 867 |
| 2 | 705, 440, 452, 170, 867 |
| 2 | 705, 220, 226, 85, 867 |
| 3 | 705, 110, 113, 85, 867 |
| 5 | 235, 110, 113, 85, 289 |
| 17 | 47, 22, 113, 17, 289 |
| 47, 22, 113, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 17 x 47 x 22 x 113 x 1 x 17 = 4052080560
Therefore, the lowest common multiple of 705,880,904,340,867 is 4052080560.
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.
705 x 880 x 904 x 340 x 867 = 165324886848000
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
904 : 1, 2, 4, 8, 113, 226, 452, 904
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,880,904,340,867, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
880:2x 2x 2x 2x 5x 11
904:2x 2x 2x 113
340:2x 2x 5x 17
867:3x 17x 17
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 2x 3x 5x 5x 17 = 40800
Therefore, the value for common factors is 40800.
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 = 165324886848000/(1x40800)
LCM = 165324886848000/40800
LCM = 4052080560
Thus, we can understand that the LCM of 705,880,904,340,867 is 4052080560.
