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

Apply this formula for all numbers.

Step1:

LCM(965, 865) = 166945

GCD(965, 865) = ( 965 x 865 ) / 166945

= 965 / 865

= 965

Step2:

LCM(5, 855) = 855

GCD(5, 855) = ( 5 x 855 ) / 855

= 5 / 855

= 5

Step3:

LCM(5, 980) = 980

GCD(5, 980) = ( 5 x 980 ) / 980

= 5 / 980

= 5

So, Greatest Common Divisor of 965, 865, 855, 980 is 5
