The LCM of 668,990,523,395,187 is 232251946740.
Find LCM of 668,990,523,395,187 with Prime Factorization
| 2 | 668, 990, 523, 395, 187 |
| 5 | 334, 495, 523, 395, 187 |
| 11 | 334, 99, 523, 79, 187 |
| 334, 9, 523, 79, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 334 x 9 x 523 x 79 x 17 = 232251946740
Therefore, the lowest common multiple of 668,990,523,395,187 is 232251946740.
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.
668 x 990 x 523 x 395 x 187 = 25547714141400
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.
668 : 1, 2, 4, 167, 334, 668
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
523 : 1, 523
395 : 1, 5, 79, 395
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,990,523,395,187, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
990:2x 3x 3x 5x 11
523:523
395:5x 79
187:11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 25547714141400/(1x110)
LCM = 25547714141400/110
LCM = 232251946740
Thus, we can understand that the LCM of 668,990,523,395,187 is 232251946740.
