Given numbers are 156, 177, 540, 621

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

Apply this formula for all numbers.

Step1:

LCM(156, 177) = 9204

GCD(156, 177) = ( 156 x 177 ) / 9204

= 156 / 177

= 156

Step2:

LCM(3, 540) = 540

GCD(3, 540) = ( 3 x 540 ) / 540

= 3 / 540

= 3

Step3:

LCM(3, 621) = 621

GCD(3, 621) = ( 3 x 621 ) / 621

= 3 / 621

= 3

So, Greatest Common Divisor of 156, 177, 540, 621 is 3
