Find LCM of 242,869,459,990,845 with Prime Factorization
| 2 | 242, 869, 459, 990, 845 |
| 3 | 121, 869, 459, 495, 845 |
| 3 | 121, 869, 153, 165, 845 |
| 5 | 121, 869, 51, 55, 845 |
| 11 | 121, 869, 51, 11, 169 |
| 1, 79, 51, 11, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 1 x 79 x 51 x 11 x 169 = 7415011890
Therefore, the lowest common multiple of 242,869,459,990,845 is 7415011890.
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.
242 x 869 x 459 x 990 x 845 = 80749479482100
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.
242 : 1, 2, 11, 22, 121, 242
869 : 1, 11, 79, 869
459 : 1, 3, 9, 17, 27, 51, 153, 459
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
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,869,459,990,845, is 1.
Now, the common factors can be found like this.
242:2x 11x 11
869:11x 79
459:3x 3x 3x 17
990:2x 3x 3x 5x 11
845:5x 13x 13
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 5x 11x 11 = 10890
Therefore, the value for common factors is 10890.
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 = 80749479482100/(1x10890)
LCM = 80749479482100/10890
LCM = 7415011890
Thus, we can understand that the LCM of 242,869,459,990,845 is 7415011890.
