Given numbers are 809, 395, 610, 256
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(809, 395) = 319555
GCD(809, 395) = ( 809 x 395 ) / 319555
= 809 / 395
= 809
Step2:
LCM(1, 610) = 610
GCD(1, 610) = ( 1 x 610 ) / 610
= 1 / 610
= 1
Step3:
LCM(1, 256) = 256
GCD(1, 256) = ( 1 x 256 ) / 256
= 1 / 256
= 1
So, Greatest Common Divisor of 809, 395, 610, 256 is 1
