GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 881) = 562959
GCD(639, 881) = ( 639 x 881 ) / 562959
= 639 / 881
= 639
Step2:
LCM(1, 266) = 266
GCD(1, 266) = ( 1 x 266 ) / 266
= 1 / 266
= 1
Step3:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
So, Greatest Common Divisor of 639, 881, 266, 159 is 1
