GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(723, 249) = 60009
GCD(723, 249) = ( 723 x 249 ) / 60009
= 723 / 249
= 723
Step2:
LCM(3, 57) = 57
GCD(3, 57) = ( 3 x 57 ) / 57
= 3 / 57
= 3
Step3:
LCM(3, 804) = 804
GCD(3, 804) = ( 3 x 804 ) / 804
= 3 / 804
= 3
So, Greatest Common Divisor of 723, 249, 57, 804 is 3
