Given numbers are 686, 802, 757, 657

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

Apply this formula for all numbers.

Step1:

LCM(686, 802) = 275086

GCD(686, 802) = ( 686 x 802 ) / 275086

= 686 / 802

= 686

Step2:

LCM(2, 757) = 1514

GCD(2, 757) = ( 2 x 757 ) / 1514

= 2 / 757

= 2

Step3:

LCM(1, 657) = 657

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

= 1 / 657

= 1

So, Greatest Common Divisor of 686, 802, 757, 657 is 1
