Given numbers are 640, 928, 939, 404
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 928) = 18560
GCD(640, 928) = ( 640 x 928 ) / 18560
= 640 / 928
= 640
Step2:
LCM(32, 939) = 30048
GCD(32, 939) = ( 32 x 939 ) / 30048
= 32 / 939
= 32
Step3:
LCM(1, 404) = 404
GCD(1, 404) = ( 1 x 404 ) / 404
= 1 / 404
= 1
So, Greatest Common Divisor of 640, 928, 939, 404 is 1
