Answer:
2
Step-by-step explanation:
Since LCM of x and y is 161, this means x and y are factors of 161. The factors of 161 are:
1 , 7, 23, 161
Since x and y are prime numbers and it is given that x > y, the only possible solution for x and y is:
x = 23
y = 7
We have to find what is the remainder when x=23 is divided by y=7. We know that 7 times 3 = 21. This means, when 23 is divided by 7, the quotient is 3 and the remainder is 2.
Therefore, the answer to this question is 2.
