Find LCM of 689,500,504,447,905 with Prime Factorization
| 2 | 689, 500, 504, 447, 905 |
| 2 | 689, 250, 252, 447, 905 |
| 3 | 689, 125, 126, 447, 905 |
| 5 | 689, 125, 42, 149, 905 |
| 689, 25, 42, 149, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 689 x 25 x 42 x 149 x 181 = 1170643383000
Therefore, the lowest common multiple of 689,500,504,447,905 is 1170643383000.
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.
689 x 500 x 504 x 447 x 905 = 70238602980000
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.
689 : 1, 13, 53, 689
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
447 : 1, 3, 149, 447
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,500,504,447,905, is 1.
Now, the common factors can be found like this.
689:13x 53
500:2x 2x 5x 5x 5
504:2x 2x 2x 3x 3x 7
447:3x 149
905:5x 181
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 70238602980000/(1x60)
LCM = 70238602980000/60
LCM = 1170643383000
Thus, we can understand that the LCM of 689,500,504,447,905 is 1170643383000.
