Given numbers are 121, 667, 172, 168
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(121, 667) = 80707
GCD(121, 667) = ( 121 x 667 ) / 80707
= 121 / 667
= 121
Step2:
LCM(1, 172) = 172
GCD(1, 172) = ( 1 x 172 ) / 172
= 1 / 172
= 1
Step3:
LCM(1, 168) = 168
GCD(1, 168) = ( 1 x 168 ) / 168
= 1 / 168
= 1
So, Greatest Common Divisor of 121, 667, 172, 168 is 1
