Given numbers are 856, 191, 581, 431
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(856, 191) = 163496
GCD(856, 191) = ( 856 x 191 ) / 163496
= 856 / 191
= 856
Step2:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
Step3:
LCM(1, 431) = 431
GCD(1, 431) = ( 1 x 431 ) / 431
= 1 / 431
= 1
So, Greatest Common Divisor of 856, 191, 581, 431 is 1
