Given numbers are 691, 514, 781, 770

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

Apply this formula for all numbers.

Step1:

LCM(691, 514) = 355174

GCD(691, 514) = ( 691 x 514 ) / 355174

= 691 / 514

= 691

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 691, 514, 781, 770 is 1
