GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 836) = 286748
GCD(686, 836) = ( 686 x 836 ) / 286748
= 686 / 836
= 686
Step2:
LCM(2, 475) = 950
GCD(2, 475) = ( 2 x 475 ) / 950
= 2 / 475
= 2
Step3:
LCM(1, 856) = 856
GCD(1, 856) = ( 1 x 856 ) / 856
= 1 / 856
= 1
So, Greatest Common Divisor of 686, 836, 475, 856 is 1
