The LCM of 431,790,790,169,733 is 42178879730.
Find LCM of 431,790,790,169,733 with Prime Factorization
| 2 | 431, 790, 790, 169, 733 |
| 5 | 431, 395, 395, 169, 733 |
| 79 | 431, 79, 79, 169, 733 |
| 431, 1, 1, 169, 733 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 79 x 431 x 1 x 1 x 169 x 733 = 42178879730
Therefore, the lowest common multiple of 431,790,790,169,733 is 42178879730.
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.
431 x 790 x 790 x 169 x 733 = 33321314986700
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.
431 : 1, 431
790 : 1, 2, 5, 10, 79, 158, 395, 790
790 : 1, 2, 5, 10, 79, 158, 395, 790
169 : 1, 13, 169
733 : 1, 733
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,790,790,169,733, is 1.
Now, the common factors can be found like this.
431:431
790:2x 5x 79
790:2x 5x 79
169:13x 13
733:733
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 79 = 790
Therefore, the value for common factors is 790.
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 = 33321314986700/(1x790)
LCM = 33321314986700/790
LCM = 42178879730
Thus, we can understand that the LCM of 431,790,790,169,733 is 42178879730.
