GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 457) = 78604
GCD(172, 457) = ( 172 x 457 ) / 78604
= 172 / 457
= 172
Step2:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
Step3:
LCM(1, 113) = 113
GCD(1, 113) = ( 1 x 113 ) / 113
= 1 / 113
= 1
So, Greatest Common Divisor of 172, 457, 209, 113 is 1
