The LCM of 591,945,756,905 is 134783460.
Find LCM of 591,945,756,905 with Prime Factorization
| 3 | 591, 945, 756, 905 |
| 3 | 197, 315, 252, 905 |
| 3 | 197, 105, 84, 905 |
| 5 | 197, 35, 28, 905 |
| 7 | 197, 7, 28, 181 |
| 197, 1, 4, 181 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 7 x 197 x 1 x 4 x 181 = 134783460
Therefore, the lowest common multiple of 591,945,756,905 is 134783460.
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.
591 x 945 x 756 x 905 = 382111109100
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.
591 : 1, 3, 197, 591
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 591,945,756,905, is 1.
Now, the common factors can be found like this.
591:3x 197
945:3x 3x 3x 5x 7
756:2x 2x 3x 3x 3x 7
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.
3x 3x 3x 3x 5x 7 = 2835
Therefore, the value for common factors is 2835.
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 = 382111109100/(1x2835)
LCM = 382111109100/2835
LCM = 134783460
Thus, we can understand that the LCM of 591,945,756,905 is 134783460.
