Given numbers are 987,988,644,629,364
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,988,644,629,364 is 14107581852.
Find LCM of 987,988,644,629,364 with Prime Factorization
| 2 | 987, 988, 644, 629, 364 |
| 2 | 987, 494, 322, 629, 182 |
| 7 | 987, 247, 161, 629, 91 |
| 13 | 141, 247, 23, 629, 13 |
| 141, 19, 23, 629, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 141 x 19 x 23 x 629 x 1 = 14107581852
Therefore, the lowest common multiple of 987,988,644,629,364 is 14107581852.
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 988 x 644 x 629 x 364 = 143784474235584
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
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
629 : 1, 17, 37, 629
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,988,644,629,364, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
988:2x 2x 13x 19
644:2x 2x 7x 23
629:17x 37
364:2x 2x 7x 13
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 7x 7x 13 = 10192
Therefore, the value for common factors is 10192.
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 = 143784474235584/(1x10192)
LCM = 143784474235584/10192
LCM = 14107581852
Thus, we can understand that the LCM of 987,988,644,629,364 is 14107581852.
