The LCM of 690,881,828,667 is 105772860.
Find LCM of 690,881,828,667 with Prime Factorization
| 2 | 690, 881, 828, 667 |
| 3 | 345, 881, 414, 667 |
| 23 | 115, 881, 138, 667 |
| 5, 881, 6, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 5 x 881 x 6 x 29 = 105772860
Therefore, the lowest common multiple of 690,881,828,667 is 105772860.
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 881 x 828 x 667 = 335723057640
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
881 : 1, 881
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,881,828,667, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
881:881
828:2x 2x 3x 3x 23
667:23x 29
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 23x 23 = 3174
Therefore, the value for common factors is 3174.
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 = 335723057640/(1x3174)
LCM = 335723057640/3174
LCM = 105772860
Thus, we can understand that the LCM of 690,881,828,667 is 105772860.
