Given numbers are 161, 340, 90

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

Apply this formula for all numbers.

Step1:

LCM(161, 340) = 54740

GCD(161, 340) = ( 161 x 340 ) / 54740

= 161 / 340

= 161

Step2:

LCM(1, 90) = 90

GCD(1, 90) = ( 1 x 90 ) / 90

= 1 / 90

= 1

So, Greatest Common Divisor of 161, 340, 90 is 1
