Find LCM of 824,640,939,321,979 with Prime Factorization
| 2 | 824, 640, 939, 321, 979 |
| 2 | 412, 320, 939, 321, 979 |
| 2 | 206, 160, 939, 321, 979 |
| 3 | 103, 80, 939, 321, 979 |
| 103, 80, 313, 107, 979 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 103 x 80 x 313 x 107 x 979 = 6484093376640
Therefore, the lowest common multiple of 824,640,939,321,979 is 6484093376640.
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.
824 x 640 x 939 x 321 x 979 = 155618241039360
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
939 : 1, 3, 313, 939
321 : 1, 3, 107, 321
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,640,939,321,979, is 1.
Now, the common factors can be found like this.
824:2x 2x 2x 103
640:2x 2x 2x 2x 2x 2x 2x 5
939:3x 313
321:3x 107
979:11x 89
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 3 = 24
Therefore, the value for common factors is 24.
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 = 155618241039360/(1x24)
LCM = 155618241039360/24
LCM = 6484093376640
Thus, we can understand that the LCM of 824,640,939,321,979 is 6484093376640.
