Given numbers are 657, 861, 85, 739

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

Apply this formula for all numbers.

Step1:

LCM(657, 861) = 188559

GCD(657, 861) = ( 657 x 861 ) / 188559

= 657 / 861

= 657

Step2:

LCM(3, 85) = 255

GCD(3, 85) = ( 3 x 85 ) / 255

= 3 / 85

= 3

Step3:

LCM(1, 739) = 739

GCD(1, 739) = ( 1 x 739 ) / 739

= 1 / 739

= 1

So, Greatest Common Divisor of 657, 861, 85, 739 is 1
