Given numbers are 680, 890, 257, 769

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

Apply this formula for all numbers.

Step1:

LCM(680, 890) = 60520

GCD(680, 890) = ( 680 x 890 ) / 60520

= 680 / 890

= 680

Step2:

LCM(10, 257) = 2570

GCD(10, 257) = ( 10 x 257 ) / 2570

= 10 / 257

= 10

Step3:

LCM(1, 769) = 769

GCD(1, 769) = ( 1 x 769 ) / 769

= 1 / 769

= 1

So, Greatest Common Divisor of 680, 890, 257, 769 is 1
