Answer:
69
Step-by-step explanation:
The product of two numbers is equal to the product of their lcm and hcf whre lcm is the lowest common multiple where hcf is the highest common factor, some countries denote it as gcd, greatest common divisor
Here
HCF(3m,161)=23 and LCM(3m,161)=1449
3m*161=23*1449
483m=23*1449
M=23*1449/483=69
Therefore, the value of m is 69
