Given numbers are 161, 889, 742, 779

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

Apply this formula for all numbers.

Step1:

LCM(161, 889) = 20447

GCD(161, 889) = ( 161 x 889 ) / 20447

= 161 / 889

= 161

Step2:

LCM(7, 742) = 742

GCD(7, 742) = ( 7 x 742 ) / 742

= 7 / 742

= 7

Step3:

LCM(7, 779) = 5453

GCD(7, 779) = ( 7 x 779 ) / 5453

= 7 / 779

= 7

So, Greatest Common Divisor of 161, 889, 742, 779 is 1
