Given numbers are 285, 677, 808, 581
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 677) = 192945
GCD(285, 677) = ( 285 x 677 ) / 192945
= 285 / 677
= 285
Step2:
LCM(1, 808) = 808
GCD(1, 808) = ( 1 x 808 ) / 808
= 1 / 808
= 1
Step3:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
So, Greatest Common Divisor of 285, 677, 808, 581 is 1
