Given numbers are 969, 699, 406, 689

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

Apply this formula for all numbers.

Step1:

LCM(969, 699) = 225777

GCD(969, 699) = ( 969 x 699 ) / 225777

= 969 / 699

= 969

Step2:

LCM(3, 406) = 1218

GCD(3, 406) = ( 3 x 406 ) / 1218

= 3 / 406

= 3

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 969, 699, 406, 689 is 1
