Given numbers are 161, 112, 310, 657

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

Apply this formula for all numbers.

Step1:

LCM(161, 112) = 2576

GCD(161, 112) = ( 161 x 112 ) / 2576

= 161 / 112

= 161

Step2:

LCM(7, 310) = 2170

GCD(7, 310) = ( 7 x 310 ) / 2170

= 7 / 310

= 7

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 161, 112, 310, 657 is 1
