Given numbers are 161, 621, 838, 153

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

Apply this formula for all numbers.

Step1:

LCM(161, 621) = 4347

GCD(161, 621) = ( 161 x 621 ) / 4347

= 161 / 621

= 161

Step2:

LCM(23, 838) = 19274

GCD(23, 838) = ( 23 x 838 ) / 19274

= 23 / 838

= 23

Step3:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

So, Greatest Common Divisor of 161, 621, 838, 153 is 1
