Find LCM of 756,945,869,766 with Prime Factorization
| 2 | 756, 945, 869, 766 |
| 3 | 378, 945, 869, 383 |
| 3 | 126, 315, 869, 383 |
| 3 | 42, 105, 869, 383 |
| 7 | 14, 35, 869, 383 |
| 2, 5, 869, 383 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 2 x 5 x 869 x 383 = 1258086060
Therefore, the lowest common multiple of 756,945,869,766 is 1258086060.
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.
756 x 945 x 869 x 766 = 475556530680
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
869 : 1, 11, 79, 869
766 : 1, 2, 383, 766
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,945,869,766, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
945:3x 3x 3x 5x 7
869:11x 79
766:2x 383
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 475556530680/(1x378)
LCM = 475556530680/378
LCM = 1258086060
Thus, we can understand that the LCM of 756,945,869,766 is 1258086060.
