Given numbers are 203, 413, 418, 178
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(203, 413) = 11977
GCD(203, 413) = ( 203 x 413 ) / 11977
= 203 / 413
= 203
Step2:
LCM(7, 418) = 2926
GCD(7, 418) = ( 7 x 418 ) / 2926
= 7 / 418
= 7
Step3:
LCM(1, 178) = 178
GCD(1, 178) = ( 1 x 178 ) / 178
= 1 / 178
= 1
So, Greatest Common Divisor of 203, 413, 418, 178 is 1
