Find LCM of 380,969,255,515,649 with Prime Factorization
| 3 | 380, 969, 255, 515, 649 |
| 5 | 380, 323, 85, 515, 649 |
| 17 | 76, 323, 17, 103, 649 |
| 19 | 76, 19, 1, 103, 649 |
| 4, 1, 1, 103, 649 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 19 x 4 x 1 x 1 x 103 x 649 = 1295494860
Therefore, the lowest common multiple of 380,969,255,515,649 is 1295494860.
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.
380 x 969 x 255 x 515 x 649 = 31383362983500
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
969 : 1, 3, 17, 19, 51, 57, 323, 969
255 : 1, 3, 5, 15, 17, 51, 85, 255
515 : 1, 5, 103, 515
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,969,255,515,649, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
969:3x 17x 19
255:3x 5x 17
515:5x 103
649:11x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 17x 19 = 24225
Therefore, the value for common factors is 24225.
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 = 31383362983500/(1x24225)
LCM = 31383362983500/24225
LCM = 1295494860
Thus, we can understand that the LCM of 380,969,255,515,649 is 1295494860.
