The LCM of 772,972,627,285 is 196037820.
Find LCM of 772,972,627,285 with Prime Factorization
| 2 | 772, 972, 627, 285 |
| 2 | 386, 486, 627, 285 |
| 3 | 193, 243, 627, 285 |
| 19 | 193, 81, 209, 95 |
| 193, 81, 11, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 193 x 81 x 11 x 5 = 196037820
Therefore, the lowest common multiple of 772,972,627,285 is 196037820.
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.
772 x 972 x 627 x 285 = 134089868880
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.
772 : 1, 2, 4, 193, 386, 772
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
627 : 1, 3, 11, 19, 33, 57, 209, 627
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,972,627,285, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
972:2x 2x 3x 3x 3x 3x 3
627:3x 11x 19
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 19 = 684
Therefore, the value for common factors is 684.
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 = 134089868880/(1x684)
LCM = 134089868880/684
LCM = 196037820
Thus, we can understand that the LCM of 772,972,627,285 is 196037820.
