Given numbers are 257, 421, 926, 770

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

Apply this formula for all numbers.

Step1:

LCM(257, 421) = 108197

GCD(257, 421) = ( 257 x 421 ) / 108197

= 257 / 421

= 257

Step2:

LCM(1, 926) = 926

GCD(1, 926) = ( 1 x 926 ) / 926

= 1 / 926

= 1

Step3:

LCM(1, 770) = 770

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

= 1 / 770

= 1

So, Greatest Common Divisor of 257, 421, 926, 770 is 1
