Given numbers are 138, 966, 227, 661

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

Apply this formula for all numbers.

Step1:

LCM(138, 966) = 966

GCD(138, 966) = ( 138 x 966 ) / 966

= 138 / 966

= 138

Step2:

LCM(138, 227) = 31326

GCD(138, 227) = ( 138 x 227 ) / 31326

= 138 / 227

= 138

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 138, 966, 227, 661 is 1
