Find LCM of 772,992,160,605,122 with Prime Factorization
| 2 | 772, 992, 160, 605, 122 |
| 2 | 386, 496, 80, 605, 61 |
| 2 | 193, 248, 40, 605, 61 |
| 2 | 193, 124, 20, 605, 61 |
| 2 | 193, 62, 10, 605, 61 |
| 5 | 193, 31, 5, 605, 61 |
| 193, 31, 1, 121, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 193 x 31 x 1 x 121 x 61 = 7065683680
Therefore, the lowest common multiple of 772,992,160,605,122 is 7065683680.
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 992 x 160 x 605 x 122 = 9044075110400
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
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
605 : 1, 5, 11, 55, 121, 605
122 : 1, 2, 61, 122
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,992,160,605,122, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
992:2x 2x 2x 2x 2x 31
160:2x 2x 2x 2x 2x 5
605:5x 11x 11
122:2x 61
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 2x 2x 2x 2x 5 = 1280
Therefore, the value for common factors is 1280.
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 = 9044075110400/(1x1280)
LCM = 9044075110400/1280
LCM = 7065683680
Thus, we can understand that the LCM of 772,992,160,605,122 is 7065683680.
