Find LCM of 990,711,814,237,905 with Prime Factorization
| 2 | 990, 711, 814, 237, 905 |
| 3 | 495, 711, 407, 237, 905 |
| 3 | 165, 79, 407, 237, 905 |
| 5 | 55, 79, 407, 79, 905 |
| 11 | 11, 79, 407, 79, 181 |
| 79 | 1, 79, 37, 79, 181 |
| 1, 1, 37, 1, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 79 x 1 x 1 x 37 x 1 x 181 = 523772370
Therefore, the lowest common multiple of 990,711,814,237,905 is 523772370.
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.
990 x 711 x 814 x 237 x 905 = 122892711173100
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.
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
711 : 1, 3, 9, 79, 237, 711
814 : 1, 2, 11, 22, 37, 74, 407, 814
237 : 1, 3, 79, 237
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,711,814,237,905, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
711:3x 3x 79
814:2x 11x 37
237:3x 79
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 3x 3x 3x 5x 11x 79 = 234630
Therefore, the value for common factors is 234630.
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 = 122892711173100/(1x234630)
LCM = 122892711173100/234630
LCM = 523772370
Thus, we can understand that the LCM of 990,711,814,237,905 is 523772370.
