Given numbers are 398, 581, 765, 469
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 581) = 231238
GCD(398, 581) = ( 398 x 581 ) / 231238
= 398 / 581
= 398
Step2:
LCM(1, 765) = 765
GCD(1, 765) = ( 1 x 765 ) / 765
= 1 / 765
= 1
Step3:
LCM(1, 469) = 469
GCD(1, 469) = ( 1 x 469 ) / 469
= 1 / 469
= 1
So, Greatest Common Divisor of 398, 581, 765, 469 is 1
