Given numbers are 939,988,608,820,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,988,608,820,991 is 1507787155680.
Find LCM of 939,988,608,820,991 with Prime Factorization
| 2 | 939, 988, 608, 820, 991 |
| 2 | 939, 494, 304, 410, 991 |
| 19 | 939, 247, 152, 205, 991 |
| 939, 13, 8, 205, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 939 x 13 x 8 x 205 x 991 = 1507787155680
Therefore, the lowest common multiple of 939,988,608,820,991 is 1507787155680.
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.
939 x 988 x 608 x 820 x 991 = 458367295326720
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.
939 : 1, 3, 313, 939
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,988,608,820,991, is 1.
Now, the common factors can be found like this.
939:3x 313
988:2x 2x 13x 19
608:2x 2x 2x 2x 2x 19
820:2x 2x 5x 41
991:991
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 19 = 304
Therefore, the value for common factors is 304.
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 = 458367295326720/(1x304)
LCM = 458367295326720/304
LCM = 1507787155680
Thus, we can understand that the LCM of 939,988,608,820,991 is 1507787155680.
