The LCM of 168,520,787,960 is 68752320.
Find LCM of 168,520,787,960 with Prime Factorization
| 2 | 168, 520, 787, 960 |
| 2 | 84, 260, 787, 480 |
| 2 | 42, 130, 787, 240 |
| 3 | 21, 65, 787, 120 |
| 5 | 7, 65, 787, 40 |
| 7, 13, 787, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 13 x 787 x 8 = 68752320
Therefore, the lowest common multiple of 168,520,787,960 is 68752320.
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.
168 x 520 x 787 x 960 = 66002227200
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
787 : 1, 787
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,520,787,960, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
520:2x 2x 2x 5x 13
787:787
960:2x 2x 2x 2x 2x 2x 3x 5
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 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 66002227200/(1x960)
LCM = 66002227200/960
LCM = 68752320
Thus, we can understand that the LCM of 168,520,787,960 is 68752320.
