Given numbers are 987, 965, 855, 635

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

Apply this formula for all numbers.

Step1:

LCM(987, 965) = 952455

GCD(987, 965) = ( 987 x 965 ) / 952455

= 987 / 965

= 987

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

= 1 / 635

= 1

So, Greatest Common Divisor of 987, 965, 855, 635 is 1
