Find LCM of 756,785,646,867,999 with Prime Factorization
2 | 756, 785, 646, 867, 999 |
3 | 378, 785, 323, 867, 999 |
3 | 126, 785, 323, 289, 333 |
3 | 42, 785, 323, 289, 111 |
17 | 14, 785, 323, 289, 37 |
14, 785, 19, 17, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 17 x 14 x 785 x 19 x 17 x 37 = 120571487820
Therefore, the lowest common multiple of 756,785,646,867,999 is 120571487820.
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 785 x 646 x 867 x 999 = 332053877456280
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
785 : 1, 5, 157, 785
646 : 1, 2, 17, 19, 34, 38, 323, 646
867 : 1, 3, 17, 51, 289, 867
999 : 1, 3, 9, 27, 37, 111, 333, 999
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,785,646,867,999, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
785:5x 157
646:2x 17x 19
867:3x 17x 17
999:3x 3x 3x 37
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 3x 17 = 2754
Therefore, the value for common factors is 2754.
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 = 332053877456280/(1x2754)
LCM = 332053877456280/2754
LCM = 120571487820
Thus, we can understand that the LCM of 756,785,646,867,999 is 120571487820.
