Given numbers are 809, 808, 657, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(809, 808) = 653672
GCD(809, 808) = ( 809 x 808 ) / 653672
= 809 / 808
= 809
Step2:
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
= 1 / 657
= 1
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 809, 808, 657, 790 is 1
