Given numbers are 169, 716, 257, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(169, 716) = 121004
GCD(169, 716) = ( 169 x 716 ) / 121004
= 169 / 716
= 169
Step2:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 169, 716, 257, 805 is 1
