Given numbers are 822, 511, 403, 255
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(822, 511) = 420042
GCD(822, 511) = ( 822 x 511 ) / 420042
= 822 / 511
= 822
Step2:
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
= 1 / 403
= 1
Step3:
LCM(1, 255) = 255
GCD(1, 255) = ( 1 x 255 ) / 255
= 1 / 255
= 1
So, Greatest Common Divisor of 822, 511, 403, 255 is 1
