Given numbers are 168,427,857,558,623
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 168,427,857,558,623 is 72693050472.
Find LCM of 168,427,857,558,623 with Prime Factorization
| 2 | 168, 427, 857, 558, 623 |
| 3 | 84, 427, 857, 279, 623 |
| 7 | 28, 427, 857, 93, 623 |
| 4, 61, 857, 93, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 4 x 61 x 857 x 93 x 89 = 72693050472
Therefore, the lowest common multiple of 168,427,857,558,623 is 72693050472.
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.
168 x 427 x 857 x 558 x 623 = 21371756838768
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
427 : 1, 7, 61, 427
857 : 1, 857
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
623 : 1, 7, 89, 623
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,427,857,558,623, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
427:7x 61
857:857
558:2x 3x 3x 31
623:7x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 7 = 294
Therefore, the value for common factors is 294.
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 = 21371756838768/(1x294)
LCM = 21371756838768/294
LCM = 72693050472
Thus, we can understand that the LCM of 168,427,857,558,623 is 72693050472.
