Prime factors of 235 are 5 x 47
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 398, 604, 505, 235
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 604) = 120196
GCD(398, 604) = ( 398 x 604 ) / 120196
= 398 / 604
= 398
Step2:
LCM(2, 505) = 1010
GCD(2, 505) = ( 2 x 505 ) / 1010
= 2 / 505
= 2
Step3:
LCM(1, 235) = 235
GCD(1, 235) = ( 1 x 235 ) / 235
= 1 / 235
= 1
So, Greatest Common Divisor of 398, 604, 505, 235 is 1
