The LCM of 361,783,969,661,957 is 34939125441.
Find LCM of 361,783,969,661,957 with Prime Factorization
| 3 | 361, 783, 969, 661, 957 |
| 19 | 361, 261, 323, 661, 319 |
| 29 | 19, 261, 17, 661, 319 |
| 19, 9, 17, 661, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 29 x 19 x 9 x 17 x 661 x 11 = 34939125441
Therefore, the lowest common multiple of 361,783,969,661,957 is 34939125441.
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.
361 x 783 x 969 x 661 x 957 = 173263123061919
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.
361 : 1, 19, 361
783 : 1, 3, 9, 27, 29, 87, 261, 783
969 : 1, 3, 17, 19, 51, 57, 323, 969
661 : 1, 661
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,783,969,661,957, is 1.
Now, the common factors can be found like this.
361:19x 19
783:3x 3x 3x 29
969:3x 17x 19
661:661
957:3x 11x 29
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 19x 29 = 4959
Therefore, the value for common factors is 4959.
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 = 173263123061919/(1x4959)
LCM = 173263123061919/4959
LCM = 34939125441
Thus, we can understand that the LCM of 361,783,969,661,957 is 34939125441.
