The list of prime factors of all numbers are
Prime factors of 398 are 2 x 199
Prime factors of 455 are 5 x 7 x 13
Prime factors of 235 are 5 x 47
Prime factors of 246 are 2 x 3 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 398, 455, 235, 246
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 455) = 181090
GCD(398, 455) = ( 398 x 455 ) / 181090
= 398 / 455
= 398
Step2:
LCM(1, 235) = 235
GCD(1, 235) = ( 1 x 235 ) / 235
= 1 / 235
= 1
Step3:
LCM(1, 246) = 246
GCD(1, 246) = ( 1 x 246 ) / 246
= 1 / 246
= 1
So, Greatest Common Divisor of 398, 455, 235, 246 is 1
