Given numbers are 987,789,711,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,789,711,793 is 48785912721.
Find LCM of 987,789,711,793 with Prime Factorization
| 3 | 987, 789, 711, 793 |
| 329, 263, 237, 793 |
Multiply the prime numbers at the bottom and the left side.
3 x 329 x 263 x 237 x 793 = 48785912721
Therefore, the lowest common multiple of 987,789,711,793 is 48785912721.
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.
987 x 789 x 711 x 793 = 439073214489
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
789 : 1, 3, 263, 789
711 : 1, 3, 9, 79, 237, 711
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,789,711,793, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
789:3x 263
711:3x 3x 79
793:13x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 439073214489/(1x9)
LCM = 439073214489/9
LCM = 48785912721
Thus, we can understand that the LCM of 987,789,711,793 is 48785912721.
