Given numbers are 345, 248, 161

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(345, 248) = 85560

GCD(345, 248) = ( 345 x 248 ) / 85560

= 345 / 248

= 345

Step2:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 345, 248, 161 is 1
