The LCM of 706,667,348,920,805 is 197778840.
Find LCM of 706,667,348,920,805 with Prime Factorization
| 2 | 706, 667, 348, 920, 805 |
| 2 | 353, 667, 174, 460, 805 |
| 5 | 353, 667, 87, 230, 805 |
| 23 | 353, 667, 87, 46, 161 |
| 29 | 353, 29, 87, 2, 7 |
| 353, 1, 3, 2, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 29 x 353 x 1 x 3 x 2 x 7 = 197778840
Therefore, the lowest common multiple of 706,667,348,920,805 is 197778840.
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.
706 x 667 x 348 x 920 x 805 = 121365007377600
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.
706 : 1, 2, 353, 706
667 : 1, 23, 29, 667
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,667,348,920,805, is 1.
Now, the common factors can be found like this.
706:2x 353
667:23x 29
348:2x 2x 3x 29
920:2x 2x 2x 5x 23
805:5x 7x 23
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 5x 23x 23x 29 = 613640
Therefore, the value for common factors is 613640.
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 = 121365007377600/(1x613640)
LCM = 121365007377600/613640
LCM = 197778840
Thus, we can understand that the LCM of 706,667,348,920,805 is 197778840.
