GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 355) = 140935
GCD(397, 355) = ( 397 x 355 ) / 140935
= 397 / 355
= 397
Step2:
LCM(1, 808) = 808
GCD(1, 808) = ( 1 x 808 ) / 808
= 1 / 808
= 1
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 397, 355, 808, 809 is 1
