Given numbers are 401, 422, 19, 287
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 422) = 169222
GCD(401, 422) = ( 401 x 422 ) / 169222
= 401 / 422
= 401
Step2:
LCM(1, 19) = 19
GCD(1, 19) = ( 1 x 19 ) / 19
= 1 / 19
= 1
Step3:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
So, Greatest Common Divisor of 401, 422, 19, 287 is 1
