Given numbers are 325, 966, 387, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(325, 966) = 313950
GCD(325, 966) = ( 325 x 966 ) / 313950
= 325 / 966
= 325
Step2:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 325, 966, 387, 689 is 1
