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

Apply this formula for all numbers.

Step1:

LCM(621, 969) = 200583

GCD(621, 969) = ( 621 x 969 ) / 200583

= 621 / 969

= 621

Step2:

LCM(3, 270) = 270

GCD(3, 270) = ( 3 x 270 ) / 270

= 3 / 270

= 3

Step3:

LCM(3, 909) = 909

GCD(3, 909) = ( 3 x 909 ) / 909

= 3 / 909

= 3

So, Greatest Common Divisor of 621, 969, 270, 909 is 3
