Given numbers are 161, 193, 19, 238
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 193) = 31073
GCD(161, 193) = ( 161 x 193 ) / 31073
= 161 / 193
= 161
Step2:
LCM(1, 19) = 19
GCD(1, 19) = ( 1 x 19 ) / 19
= 1 / 19
= 1
Step3:
LCM(1, 238) = 238
GCD(1, 238) = ( 1 x 238 ) / 238
= 1 / 238
= 1
So, Greatest Common Divisor of 161, 193, 19, 238 is 1
