The list of prime factors of all numbers are
Prime factors of 684 are 2 x 2 x 3 x 3 x 19
Prime factors of 455 are 5 x 7 x 13
Prime factors of 195 are 3 x 5 x 13
Prime factors of 154 are 2 x 7 x 11
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 684, 455, 195, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 455) = 311220
GCD(684, 455) = ( 684 x 455 ) / 311220
= 684 / 455
= 684
Step2:
LCM(1, 195) = 195
GCD(1, 195) = ( 1 x 195 ) / 195
= 1 / 195
= 1
Step3:
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
= 1 / 154
= 1
So, Greatest Common Divisor of 684, 455, 195, 154 is 1
