GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(171, 791) = 135261
GCD(171, 791) = ( 171 x 791 ) / 135261
= 171 / 791
= 171
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 558) = 558
GCD(1, 558) = ( 1 x 558 ) / 558
= 1 / 558
= 1
So, Greatest Common Divisor of 171, 791, 642, 558 is 1
