Given numbers are 231, 206, 18, 355
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 206) = 47586
GCD(231, 206) = ( 231 x 206 ) / 47586
= 231 / 206
= 231
Step2:
LCM(1, 18) = 18
GCD(1, 18) = ( 1 x 18 ) / 18
= 1 / 18
= 1
Step3:
LCM(1, 355) = 355
GCD(1, 355) = ( 1 x 355 ) / 355
= 1 / 355
= 1
So, Greatest Common Divisor of 231, 206, 18, 355 is 1
