Answer:
The value of A is 14.
Step-by-step explanation:
We have LCM of (A,6) = 42
Assume A as 42/6 = 7
But we also have GCF (A,6) = 2
7 cannot be divided by 2 so, value of A is not 7.
Assuming next value,
A = 42 x 2 / 6 = 14
We know that LCM of 14 and 6 is 42
GCF of 14 and 6 is 2.
The value of A is 14.
