Given numbers are 238, 103, 455, 181
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(238, 103) = 24514
GCD(238, 103) = ( 238 x 103 ) / 24514
= 238 / 103
= 238
Step2:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
Step3:
LCM(1, 181) = 181
GCD(1, 181) = ( 1 x 181 ) / 181
= 1 / 181
= 1
So, Greatest Common Divisor of 238, 103, 455, 181 is 1
