Given numbers are 657, 890, 866, 840

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

Apply this formula for all numbers.

Step1:

LCM(657, 890) = 584730

GCD(657, 890) = ( 657 x 890 ) / 584730

= 657 / 890

= 657

Step2:

LCM(1, 866) = 866

GCD(1, 866) = ( 1 x 866 ) / 866

= 1 / 866

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 657, 890, 866, 840 is 1
