| 827, 5, 16, 23, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 827 x 5 x 16 x 23 x 157 = 80271663360
Therefore, the lowest common multiple of 827,560,768,644,942 is 80271663360.
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.
827 x 560 x 768 x 644 x 942 = 215770231111680
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.
827 : 1, 827
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 827,560,768,644,942, is 1.
Now, the common factors can be found like this.
827:827
560:2x 2x 2x 2x 5x 7
768:2x 2x 2x 2x 2x 2x 2x 2x 3
644:2x 2x 7x 23
942:2x 3x 157
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 2x 2x 2x 2x 3x 7 = 2688
Therefore, the value for common factors is 2688.
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 = 215770231111680/(1x2688)
LCM = 215770231111680/2688
LCM = 80271663360
Thus, we can understand that the LCM of 827,560,768,644,942 is 80271663360.
