Given numbers are 285, 532, 203, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 532) = 7980
GCD(285, 532) = ( 285 x 532 ) / 7980
= 285 / 532
= 285
Step2:
LCM(19, 203) = 3857
GCD(19, 203) = ( 19 x 203 ) / 3857
= 19 / 203
= 19
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 285, 532, 203, 815 is 1
