GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 558) = 143406
GCD(257, 558) = ( 257 x 558 ) / 143406
= 257 / 558
= 257
Step2:
LCM(1, 985) = 985
GCD(1, 985) = ( 1 x 985 ) / 985
= 1 / 985
= 1
Step3:
LCM(1, 779) = 779
GCD(1, 779) = ( 1 x 779 ) / 779
= 1 / 779
= 1
So, Greatest Common Divisor of 257, 558, 985, 779 is 1
