The list of prime factors of all numbers are
Prime factors of 404 are 2 x 2 x 101
Prime factors of 645 are 3 x 5 x 43
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 633 are 3 x 211
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 404, 645, 420, 633
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(404, 645) = 260580
GCD(404, 645) = ( 404 x 645 ) / 260580
= 404 / 645
= 404
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 633) = 633
GCD(1, 633) = ( 1 x 633 ) / 633
= 1 / 633
= 1
So, Greatest Common Divisor of 404, 645, 420, 633 is 1
