GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 259) = 73815
GCD(285, 259) = ( 285 x 259 ) / 73815
= 285 / 259
= 285
Step2:
LCM(1, 885) = 885
GCD(1, 885) = ( 1 x 885 ) / 885
= 1 / 885
= 1
Step3:
LCM(1, 320) = 320
GCD(1, 320) = ( 1 x 320 ) / 320
= 1 / 320
= 1
So, Greatest Common Divisor of 285, 259, 885, 320 is 1
