Given numbers are 931, 424, 923, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(931, 424) = 394744
GCD(931, 424) = ( 931 x 424 ) / 394744
= 931 / 424
= 931
Step2:
LCM(1, 923) = 923
GCD(1, 923) = ( 1 x 923 ) / 923
= 1 / 923
= 1
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 931, 424, 923, 921 is 1
