Given numbers are 161, 280, 823, 771

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

Apply this formula for all numbers.

Step1:

LCM(161, 280) = 6440

GCD(161, 280) = ( 161 x 280 ) / 6440

= 161 / 280

= 161

Step2:

LCM(7, 823) = 5761

GCD(7, 823) = ( 7 x 823 ) / 5761

= 7 / 823

= 7

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 161, 280, 823, 771 is 1
