Given numbers are 690,613,834,843
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,613,834,843 is 16520785230.
Find LCM of 690,613,834,843 with Prime Factorization
| 2 | 690, 613, 834, 843 |
| 3 | 345, 613, 417, 843 |
| 115, 613, 139, 281 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 115 x 613 x 139 x 281 = 16520785230
Therefore, the lowest common multiple of 690,613,834,843 is 16520785230.
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.
690 x 613 x 834 x 843 = 297374134140
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
613 : 1, 613
834 : 1, 2, 3, 6, 139, 278, 417, 834
843 : 1, 3, 281, 843
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,613,834,843, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
613:613
834:2x 3x 139
843:3x 281
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 3 = 18
Therefore, the value for common factors is 18.
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 = 297374134140/(1x18)
LCM = 297374134140/18
LCM = 16520785230
Thus, we can understand that the LCM of 690,613,834,843 is 16520785230.
