Given numbers are 161, 455, 118, 571

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

Apply this formula for all numbers.

Step1:

LCM(161, 455) = 10465

GCD(161, 455) = ( 161 x 455 ) / 10465

= 161 / 455

= 161

Step2:

LCM(7, 118) = 826

GCD(7, 118) = ( 7 x 118 ) / 826

= 7 / 118

= 7

Step3:

LCM(1, 571) = 571

GCD(1, 571) = ( 1 x 571 ) / 571

= 1 / 571

= 1

So, Greatest Common Divisor of 161, 455, 118, 571 is 1
