Given numbers are 257, 667, 688, 797
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 667) = 171419
GCD(257, 667) = ( 257 x 667 ) / 171419
= 257 / 667
= 257
Step2:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
Step3:
LCM(1, 797) = 797
GCD(1, 797) = ( 1 x 797 ) / 797
= 1 / 797
= 1
So, Greatest Common Divisor of 257, 667, 688, 797 is 1
