Given numbers are 331, 245, 604, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(331, 245) = 81095
GCD(331, 245) = ( 331 x 245 ) / 81095
= 331 / 245
= 331
Step2:
LCM(1, 604) = 604
GCD(1, 604) = ( 1 x 604 ) / 604
= 1 / 604
= 1
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 331, 245, 604, 393 is 1
