Given numbers are 808, 505, 397, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(808, 505) = 4040
GCD(808, 505) = ( 808 x 505 ) / 4040
= 808 / 505
= 808
Step2:
LCM(101, 397) = 40097
GCD(101, 397) = ( 101 x 397 ) / 40097
= 101 / 397
= 101
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 808, 505, 397, 689 is 1
