Find LCM of 765,899,551,399,909 with Prime Factorization
| 3 | 765, 899, 551, 399, 909 |
| 3 | 255, 899, 551, 133, 303 |
| 19 | 85, 899, 551, 133, 101 |
| 29 | 85, 899, 29, 7, 101 |
| 85, 31, 1, 7, 101 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 19 x 29 x 85 x 31 x 1 x 7 x 101 = 9238344255
Therefore, the lowest common multiple of 765,899,551,399,909 is 9238344255.
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.
765 x 899 x 551 x 399 x 909 = 137438847481635
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
899 : 1, 29, 31, 899
551 : 1, 19, 29, 551
399 : 1, 3, 7, 19, 21, 57, 133, 399
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,899,551,399,909, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
899:29x 31
551:19x 29
399:3x 7x 19
909:3x 3x 101
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 19x 29 = 14877
Therefore, the value for common factors is 14877.
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 = 137438847481635/(1x14877)
LCM = 137438847481635/14877
LCM = 9238344255
Thus, we can understand that the LCM of 765,899,551,399,909 is 9238344255.
