Given numbers are 161, 728, 785, 228
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 728) = 16744
GCD(161, 728) = ( 161 x 728 ) / 16744
= 161 / 728
= 161
Step2:
LCM(7, 785) = 5495
GCD(7, 785) = ( 7 x 785 ) / 5495
= 7 / 785
= 7
Step3:
LCM(1, 228) = 228
GCD(1, 228) = ( 1 x 228 ) / 228
= 1 / 228
= 1
So, Greatest Common Divisor of 161, 728, 785, 228 is 1
