Given numbers are 253, 198, 191, 181
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(253, 198) = 4554
GCD(253, 198) = ( 253 x 198 ) / 4554
= 253 / 198
= 253
Step2:
LCM(11, 191) = 2101
GCD(11, 191) = ( 11 x 191 ) / 2101
= 11 / 191
= 11
Step3:
LCM(1, 181) = 181
GCD(1, 181) = ( 1 x 181 ) / 181
= 1 / 181
= 1
So, Greatest Common Divisor of 253, 198, 191, 181 is 1
