Find LCM of 771,988,171,792 with Prime Factorization
| 2 | 771, 988, 171, 792 |
| 2 | 771, 494, 171, 396 |
| 3 | 771, 247, 171, 198 |
| 3 | 257, 247, 57, 66 |
| 19 | 257, 247, 19, 22 |
| 257, 13, 1, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 257 x 13 x 1 x 22 = 50275368
Therefore, the lowest common multiple of 771,988,171,792 is 50275368.
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.
771 x 988 x 171 x 792 = 103165055136
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.
771 : 1, 3, 257, 771
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
171 : 1, 3, 9, 19, 57, 171
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,988,171,792, is 1.
Now, the common factors can be found like this.
771:3x 257
988:2x 2x 13x 19
171:3x 3x 19
792:2x 2x 2x 3x 3x 11
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 3x 19 = 2052
Therefore, the value for common factors is 2052.
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 = 103165055136/(1x2052)
LCM = 103165055136/2052
LCM = 50275368
Thus, we can understand that the LCM of 771,988,171,792 is 50275368.
