Find LCM of 172,678,791,656,960 with Prime Factorization
2 | 172, 678, 791, 656, 960 |
2 | 86, 339, 791, 328, 480 |
2 | 43, 339, 791, 164, 240 |
2 | 43, 339, 791, 82, 120 |
3 | 43, 339, 791, 41, 60 |
113 | 43, 113, 791, 41, 20 |
43, 1, 7, 41, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 113 x 43 x 1 x 7 x 41 x 20 = 1338751680
Therefore, the lowest common multiple of 172,678,791,656,960 is 1338751680.
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.
172 x 678 x 791 x 656 x 960 = 58091112898560
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.
172 : 1, 2, 4, 43, 86, 172
678 : 1, 2, 3, 6, 113, 226, 339, 678
791 : 1, 7, 113, 791
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
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 172,678,791,656,960, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
678:2x 3x 113
791:7x 113
656:2x 2x 2x 2x 41
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 2x 3x 113 = 43392
Therefore, the value for common factors is 43392.
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 = 58091112898560/(1x43392)
LCM = 58091112898560/43392
LCM = 1338751680
Thus, we can understand that the LCM of 172,678,791,656,960 is 1338751680.
