GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 823) = 320147
GCD(389, 823) = ( 389 x 823 ) / 320147
= 389 / 823
= 389
Step2:
LCM(1, 136) = 136
GCD(1, 136) = ( 1 x 136 ) / 136
= 1 / 136
= 1
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 389, 823, 136, 139 is 1
