Given numbers are 538, 668, 168, 163
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(538, 668) = 179692
GCD(538, 668) = ( 538 x 668 ) / 179692
= 538 / 668
= 538
Step2:
LCM(2, 168) = 168
GCD(2, 168) = ( 2 x 168 ) / 168
= 2 / 168
= 2
Step3:
LCM(2, 163) = 326
GCD(2, 163) = ( 2 x 163 ) / 326
= 2 / 163
= 2
So, Greatest Common Divisor of 538, 668, 168, 163 is 1
