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

Apply this formula for all numbers.

Step1:

LCM(987, 753) = 247737

GCD(987, 753) = ( 987 x 753 ) / 247737

= 987 / 753

= 987

Step2:

LCM(3, 177) = 177

GCD(3, 177) = ( 3 x 177 ) / 177

= 3 / 177

= 3

Step3:

LCM(3, 171) = 171

GCD(3, 171) = ( 3 x 171 ) / 171

= 3 / 171

= 3

So, Greatest Common Divisor of 987, 753, 177, 171 is 3
