GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 733) = 502838
GCD(686, 733) = ( 686 x 733 ) / 502838
= 686 / 733
= 686
Step2:
LCM(1, 153) = 153
GCD(1, 153) = ( 1 x 153 ) / 153
= 1 / 153
= 1
Step3:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
So, Greatest Common Divisor of 686, 733, 153, 197 is 1
