Find LCM of 729,987,551,909,203 with Prime Factorization
| 3 | 729, 987, 551, 909, 203 |
| 3 | 243, 329, 551, 303, 203 |
| 7 | 81, 329, 551, 101, 203 |
| 29 | 81, 47, 551, 101, 29 |
| 81, 47, 19, 101, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 29 x 81 x 47 x 19 x 101 x 1 = 13347391491
Therefore, the lowest common multiple of 729,987,551,909,203 is 13347391491.
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.
729 x 987 x 551 x 909 x 203 = 73157052762171
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.
729 : 1, 3, 9, 27, 81, 243, 729
987 : 1, 3, 7, 21, 47, 141, 329, 987
551 : 1, 19, 29, 551
909 : 1, 3, 9, 101, 303, 909
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,987,551,909,203, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
987:3x 7x 47
551:19x 29
909:3x 3x 101
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7x 29 = 5481
Therefore, the value for common factors is 5481.
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 = 73157052762171/(1x5481)
LCM = 73157052762171/5481
LCM = 13347391491
Thus, we can understand that the LCM of 729,987,551,909,203 is 13347391491.
