Given numbers are 775, 665, 109, 657

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

Apply this formula for all numbers.

Step1:

LCM(775, 665) = 103075

GCD(775, 665) = ( 775 x 665 ) / 103075

= 775 / 665

= 775

Step2:

LCM(5, 109) = 545

GCD(5, 109) = ( 5 x 109 ) / 545

= 5 / 109

= 5

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 775, 665, 109, 657 is 1
