GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(457, 558) = 255006
GCD(457, 558) = ( 457 x 558 ) / 255006
= 457 / 558
= 457
Step2:
LCM(1, 726) = 726
GCD(1, 726) = ( 1 x 726 ) / 726
= 1 / 726
= 1
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 457, 558, 726, 142 is 1
