Given numbers are 207, 153, 851, 109

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

Apply this formula for all numbers.

Step1:

LCM(207, 153) = 3519

GCD(207, 153) = ( 207 x 153 ) / 3519

= 207 / 153

= 207

Step2:

LCM(9, 851) = 7659

GCD(9, 851) = ( 9 x 851 ) / 7659

= 9 / 851

= 9

Step3:

LCM(1, 109) = 109

GCD(1, 109) = ( 1 x 109 ) / 109

= 1 / 109

= 1

So, Greatest Common Divisor of 207, 153, 851, 109 is 1
