Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 17 x 41 x 29 x 8 x 5 x 1 = 271662720
Therefore, the lowest common multiple of 861,986,896,240,816 is 271662720.
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.
861 x 986 x 896 x 240 x 816 = 148966795837440
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
986 : 1, 2, 17, 29, 34, 58, 493, 986
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,986,896,240,816, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
986:2x 17x 29
896:2x 2x 2x 2x 2x 2x 2x 7
240:2x 2x 2x 2x 3x 5
816:2x 2x 2x 2x 3x 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 2x 2x 2x 2x 2x 2x 3x 3x 7x 17 = 548352
Therefore, the value for common factors is 548352.
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 = 148966795837440/(1x548352)
LCM = 148966795837440/548352
LCM = 271662720
Thus, we can understand that the LCM of 861,986,896,240,816 is 271662720.
