Given numbers are 109, 685, 28, 475

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

Apply this formula for all numbers.

Step1:

LCM(109, 685) = 74665

GCD(109, 685) = ( 109 x 685 ) / 74665

= 109 / 685

= 109

Step2:

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

= 1 / 28

= 1

Step3:

LCM(1, 475) = 475

GCD(1, 475) = ( 1 x 475 ) / 475

= 1 / 475

= 1

So, Greatest Common Divisor of 109, 685, 28, 475 is 1
