The LCM of 991,986,585,684,608 is 173772087840.
Find LCM of 991,986,585,684,608 with Prime Factorization
| 2 | 991, 986, 585, 684, 608 |
| 2 | 991, 493, 585, 342, 304 |
| 3 | 991, 493, 585, 171, 152 |
| 3 | 991, 493, 195, 57, 152 |
| 19 | 991, 493, 65, 19, 152 |
| 991, 493, 65, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 991 x 493 x 65 x 1 x 8 = 173772087840
Therefore, the lowest common multiple of 991,986,585,684,608 is 173772087840.
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.
991 x 986 x 585 x 684 x 608 = 237720216165120
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.
991 : 1, 991
986 : 1, 2, 17, 29, 34, 58, 493, 986
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,986,585,684,608, is 1.
Now, the common factors can be found like this.
991:991
986:2x 17x 29
585:3x 3x 5x 13
684:2x 2x 3x 3x 19
608:2x 2x 2x 2x 2x 19
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 3x 3x 19 = 1368
Therefore, the value for common factors is 1368.
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 = 237720216165120/(1x1368)
LCM = 237720216165120/1368
LCM = 173772087840
Thus, we can understand that the LCM of 991,986,585,684,608 is 173772087840.
