Given numbers are 869, 957, 291, 689

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

Apply this formula for all numbers.

Step1:

LCM(869, 957) = 75603

GCD(869, 957) = ( 869 x 957 ) / 75603

= 869 / 957

= 869

Step2:

LCM(11, 291) = 3201

GCD(11, 291) = ( 11 x 291 ) / 3201

= 11 / 291

= 11

Step3:

LCM(1, 689) = 689

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

= 1 / 689

= 1

So, Greatest Common Divisor of 869, 957, 291, 689 is 1
