The LCM of 728,432,342,881 is 658043568.
Find LCM of 728,432,342,881 with Prime Factorization
| 2 | 728, 432, 342, 881 |
| 2 | 364, 216, 171, 881 |
| 2 | 182, 108, 171, 881 |
| 3 | 91, 54, 171, 881 |
| 3 | 91, 18, 57, 881 |
| 91, 6, 19, 881 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 91 x 6 x 19 x 881 = 658043568
Therefore, the lowest common multiple of 728,432,342,881 is 658043568.
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.
728 x 432 x 342 x 881 = 94758273792
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
881 : 1, 881
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,432,342,881, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
432:2x 2x 2x 2x 3x 3x 3
342:2x 3x 3x 19
881:881
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 3 = 144
Therefore, the value for common factors is 144.
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 = 94758273792/(1x144)
LCM = 94758273792/144
LCM = 658043568
Thus, we can understand that the LCM of 728,432,342,881 is 658043568.
