GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 495) = 21285
GCD(387, 495) = ( 387 x 495 ) / 21285
= 387 / 495
= 387
Step2:
LCM(9, 804) = 2412
GCD(9, 804) = ( 9 x 804 ) / 2412
= 9 / 804
= 9
Step3:
LCM(3, 689) = 2067
GCD(3, 689) = ( 3 x 689 ) / 2067
= 3 / 689
= 3
So, Greatest Common Divisor of 387, 495, 804, 689 is 1
