GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 121) = 83006
GCD(686, 121) = ( 686 x 121 ) / 83006
= 686 / 121
= 686
Step2:
LCM(1, 452) = 452
GCD(1, 452) = ( 1 x 452 ) / 452
= 1 / 452
= 1
Step3:
LCM(1, 928) = 928
GCD(1, 928) = ( 1 x 928 ) / 928
= 1 / 928
= 1
So, Greatest Common Divisor of 686, 121, 452, 928 is 1
