The LCM of 217,855,589,774 is 15956010.
Find LCM of 217,855,589,774 with Prime Factorization
| 3 | 217, 855, 589, 774 |
| 3 | 217, 285, 589, 258 |
| 19 | 217, 95, 589, 86 |
| 31 | 217, 5, 31, 86 |
| 7, 5, 1, 86 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 19 x 31 x 7 x 5 x 1 x 86 = 15956010
Therefore, the lowest common multiple of 217,855,589,774 is 15956010.
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.
217 x 855 x 589 x 774 = 84582809010
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.
217 : 1, 7, 31, 217
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
589 : 1, 19, 31, 589
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,855,589,774, is 1.
Now, the common factors can be found like this.
217:7x 31
855:3x 3x 5x 19
589:19x 31
774:2x 3x 3x 43
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 19x 31 = 5301
Therefore, the value for common factors is 5301.
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 = 84582809010/(1x5301)
LCM = 84582809010/5301
LCM = 15956010
Thus, we can understand that the LCM of 217,855,589,774 is 15956010.
