Given numbers are 684,649,474,395,223
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,649,474,395,223 is 39102340860.
Find LCM of 684,649,474,395,223 with Prime Factorization
| 2 | 684, 649, 474, 395, 223 |
| 3 | 342, 649, 237, 395, 223 |
| 79 | 114, 649, 79, 395, 223 |
| 114, 649, 1, 5, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 79 x 114 x 649 x 1 x 5 x 223 = 39102340860
Therefore, the lowest common multiple of 684,649,474,395,223 is 39102340860.
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.
684 x 649 x 474 x 395 x 223 = 18534509567640
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
649 : 1, 11, 59, 649
474 : 1, 2, 3, 6, 79, 158, 237, 474
395 : 1, 5, 79, 395
223 : 1, 223
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,649,474,395,223, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
649:11x 59
474:2x 3x 79
395:5x 79
223:223
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 79 = 474
Therefore, the value for common factors is 474.
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 = 18534509567640/(1x474)
LCM = 18534509567640/474
LCM = 39102340860
Thus, we can understand that the LCM of 684,649,474,395,223 is 39102340860.
