Given numbers are 168,871,280,631,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 168,871,280,631,722 is 166661007240.
Find LCM of 168,871,280,631,722 with Prime Factorization
| 2 | 168, 871, 280, 631, 722 |
| 2 | 84, 871, 140, 631, 361 |
| 2 | 42, 871, 70, 631, 361 |
| 7 | 21, 871, 35, 631, 361 |
| 3, 871, 5, 631, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 3 x 871 x 5 x 631 x 361 = 166661007240
Therefore, the lowest common multiple of 168,871,280,631,722 is 166661007240.
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 871 x 280 x 631 x 722 = 18666032810880
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
871 : 1, 13, 67, 871
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
631 : 1, 631
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,871,280,631,722, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
871:13x 67
280:2x 2x 2x 5x 7
631:631
722:2x 19x 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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 18666032810880/(1x112)
LCM = 18666032810880/112
LCM = 166661007240
Thus, we can understand that the LCM of 168,871,280,631,722 is 166661007240.
