Find LCM of 792,138,560,759,931 with Prime Factorization
| 2 | 792, 138, 560, 759, 931 |
| 2 | 396, 69, 280, 759, 931 |
| 2 | 198, 69, 140, 759, 931 |
| 3 | 99, 69, 70, 759, 931 |
| 7 | 33, 23, 70, 253, 931 |
| 11 | 33, 23, 10, 253, 133 |
| 23 | 3, 23, 10, 23, 133 |
| 3, 1, 10, 1, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 11 x 23 x 3 x 1 x 10 x 1 x 133 = 169590960
Therefore, the lowest common multiple of 792,138,560,759,931 is 169590960.
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.
792 x 138 x 560 x 759 x 931 = 43249764983040
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.
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
138 : 1, 2, 3, 6, 23, 46, 69, 138
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
759 : 1, 3, 11, 23, 33, 69, 253, 759
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,138,560,759,931, is 1.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
138:2x 3x 23
560:2x 2x 2x 2x 5x 7
759:3x 11x 23
931:7x 7x 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 2x 2x 3x 3x 7x 11x 23 = 255024
Therefore, the value for common factors is 255024.
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 = 43249764983040/(1x255024)
LCM = 43249764983040/255024
LCM = 169590960
Thus, we can understand that the LCM of 792,138,560,759,931 is 169590960.
