Find LCM of 765,115,745,969,153 with Prime Factorization
| 3 | 765, 115, 745, 969, 153 |
| 3 | 255, 115, 745, 323, 51 |
| 5 | 85, 115, 745, 323, 17 |
| 17 | 17, 23, 149, 323, 17 |
| 1, 23, 149, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 17 x 1 x 23 x 149 x 19 x 1 = 49811445
Therefore, the lowest common multiple of 765,115,745,969,153 is 49811445.
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 115 x 745 x 969 x 153 = 9716967633375
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
115 : 1, 5, 23, 115
745 : 1, 5, 149, 745
969 : 1, 3, 17, 19, 51, 57, 323, 969
153 : 1, 3, 9, 17, 51, 153
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,115,745,969,153, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
115:5x 23
745:5x 149
969:3x 17x 19
153:3x 3x 17
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 5x 5x 17x 17 = 195075
Therefore, the value for common factors is 195075.
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 = 9716967633375/(1x195075)
LCM = 9716967633375/195075
LCM = 49811445
Thus, we can understand that the LCM of 765,115,745,969,153 is 49811445.
