Find LCM of 771,536,864,869,765 with Prime Factorization
| 2 | 771, 536, 864, 869, 765 |
| 2 | 771, 268, 432, 869, 765 |
| 2 | 771, 134, 216, 869, 765 |
| 3 | 771, 67, 108, 869, 765 |
| 3 | 257, 67, 36, 869, 255 |
| 257, 67, 12, 869, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 257 x 67 x 12 x 869 x 85 = 1098905559840
Therefore, the lowest common multiple of 771,536,864,869,765 is 1098905559840.
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.
771 x 536 x 864 x 869 x 765 = 237363600925440
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.
771 : 1, 3, 257, 771
536 : 1, 2, 4, 8, 67, 134, 268, 536
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
869 : 1, 11, 79, 869
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,536,864,869,765, is 1.
Now, the common factors can be found like this.
771:3x 257
536:2x 2x 2x 67
864:2x 2x 2x 2x 2x 3x 3x 3
869:11x 79
765:3x 3x 5x 17
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 237363600925440/(1x216)
LCM = 237363600925440/216
LCM = 1098905559840
Thus, we can understand that the LCM of 771,536,864,869,765 is 1098905559840.
