Given numbers are 869, 275, 342, 987

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

Apply this formula for all numbers.

Step1:

LCM(869, 275) = 21725

GCD(869, 275) = ( 869 x 275 ) / 21725

= 869 / 275

= 869

Step2:

LCM(11, 342) = 3762

GCD(11, 342) = ( 11 x 342 ) / 3762

= 11 / 342

= 11

Step3:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

So, Greatest Common Divisor of 869, 275, 342, 987 is 1
