Given numbers are 609, 987, 770, 969

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

Apply this formula for all numbers.

Step1:

LCM(609, 987) = 28623

GCD(609, 987) = ( 609 x 987 ) / 28623

= 609 / 987

= 609

Step2:

LCM(21, 770) = 2310

GCD(21, 770) = ( 21 x 770 ) / 2310

= 21 / 770

= 21

Step3:

LCM(7, 969) = 6783

GCD(7, 969) = ( 7 x 969 ) / 6783

= 7 / 969

= 7

So, Greatest Common Divisor of 609, 987, 770, 969 is 1
