GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(208, 164) = 8528
GCD(208, 164) = ( 208 x 164 ) / 8528
= 208 / 164
= 208
Step2:
LCM(4, 438) = 876
GCD(4, 438) = ( 4 x 438 ) / 876
= 4 / 438
= 4
Step3:
LCM(2, 161) = 322
GCD(2, 161) = ( 2 x 161 ) / 322
= 2 / 161
= 2
So, Greatest Common Divisor of 208, 164, 438, 161 is 1
