Given numbers are 398, 665, 231, 330
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 665) = 264670
GCD(398, 665) = ( 398 x 665 ) / 264670
= 398 / 665
= 398
Step2:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
Step3:
LCM(1, 330) = 330
GCD(1, 330) = ( 1 x 330 ) / 330
= 1 / 330
= 1
So, Greatest Common Divisor of 398, 665, 231, 330 is 1
