Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 35 x 31 x 19 x 8 x 9 = 142490880
Therefore, the lowest common multiple of 840,992,152,256,108 is 142490880.
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.
840 x 992 x 152 x 256 x 108 = 3501855866880
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.
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
152 : 1, 2, 4, 8, 19, 38, 76, 152
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,992,152,256,108, is 4.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
992:2x 2x 2x 2x 2x 31
152:2x 2x 2x 19
256:2x 2x 2x 2x 2x 2x 2x 2
108:2x 2x 3x 3x 3
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 2x 2x 3 = 6144
Therefore, the value for common factors is 6144.
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 = 3501855866880/(4x6144)
LCM = 3501855866880/24576
LCM = 142490880
Thus, we can understand that the LCM of 840,992,152,256,108 is 142490880.
