Given numbers are 257, 403, 579, 126
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 403) = 103571
GCD(257, 403) = ( 257 x 403 ) / 103571
= 257 / 403
= 257
Step2:
LCM(1, 579) = 579
GCD(1, 579) = ( 1 x 579 ) / 579
= 1 / 579
= 1
Step3:
LCM(1, 126) = 126
GCD(1, 126) = ( 1 x 126 ) / 126
= 1 / 126
= 1
So, Greatest Common Divisor of 257, 403, 579, 126 is 1
