The LCM of 609,105,791,388,868 is 4138654380.
Find LCM of 609,105,791,388,868 with Prime Factorization
| 2 | 609, 105, 791, 388, 868 |
| 2 | 609, 105, 791, 194, 434 |
| 3 | 609, 105, 791, 97, 217 |
| 7 | 203, 35, 791, 97, 217 |
| 29, 5, 113, 97, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 29 x 5 x 113 x 97 x 31 = 4138654380
Therefore, the lowest common multiple of 609,105,791,388,868 is 4138654380.
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.
609 x 105 x 791 x 388 x 868 = 17034701428080
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
105 : 1, 3, 5, 7, 15, 21, 35, 105
791 : 1, 7, 113, 791
388 : 1, 2, 4, 97, 194, 388
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,105,791,388,868, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
105:3x 5x 7
791:7x 113
388:2x 2x 97
868:2x 2x 7x 31
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 3x 7x 7x 7 = 4116
Therefore, the value for common factors is 4116.
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 = 17034701428080/(1x4116)
LCM = 17034701428080/4116
LCM = 4138654380
Thus, we can understand that the LCM of 609,105,791,388,868 is 4138654380.
