Given numbers are 685, 650, 29, 189

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(685, 650) = 89050

GCD(685, 650) = ( 685 x 650 ) / 89050

= 685 / 650

= 685

Step2:

LCM(5, 29) = 145

GCD(5, 29) = ( 5 x 29 ) / 145

= 5 / 29

= 5

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 685, 650, 29, 189 is 1
