The LCM of 154,693,341,945,807 is 173367810.
Find LCM of 154,693,341,945,807 with Prime Factorization
| 3 | 154, 693, 341, 945, 807 |
| 3 | 154, 231, 341, 315, 269 |
| 7 | 154, 77, 341, 105, 269 |
| 11 | 22, 11, 341, 15, 269 |
| 2, 1, 31, 15, 269 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 11 x 2 x 1 x 31 x 15 x 269 = 173367810
Therefore, the lowest common multiple of 154,693,341,945,807 is 173367810.
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.
154 x 693 x 341 x 945 x 807 = 27753239128230
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
341 : 1, 11, 31, 341
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
807 : 1, 3, 269, 807
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,693,341,945,807, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
693:3x 3x 7x 11
341:11x 31
945:3x 3x 3x 5x 7
807:3x 269
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 7x 7x 11x 11 = 160083
Therefore, the value for common factors is 160083.
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 = 27753239128230/(1x160083)
LCM = 27753239128230/160083
LCM = 173367810
Thus, we can understand that the LCM of 154,693,341,945,807 is 173367810.
