Given numbers are 320, 436, 317, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(320, 436) = 34880
GCD(320, 436) = ( 320 x 436 ) / 34880
= 320 / 436
= 320
Step2:
LCM(4, 317) = 1268
GCD(4, 317) = ( 4 x 317 ) / 1268
= 4 / 317
= 4
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 320, 436, 317, 789 is 1
