Given numbers are 657, 990, 487, 139

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

Apply this formula for all numbers.

Step1:

LCM(657, 990) = 72270

GCD(657, 990) = ( 657 x 990 ) / 72270

= 657 / 990

= 657

Step2:

LCM(9, 487) = 4383

GCD(9, 487) = ( 9 x 487 ) / 4383

= 9 / 487

= 9

Step3:

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

= 1 / 139

= 1

So, Greatest Common Divisor of 657, 990, 487, 139 is 1
