GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 804) = 131052
GCD(978, 804) = ( 978 x 804 ) / 131052
= 978 / 804
= 978
Step2:
LCM(6, 790) = 2370
GCD(6, 790) = ( 6 x 790 ) / 2370
= 6 / 790
= 6
Step3:
LCM(2, 797) = 1594
GCD(2, 797) = ( 2 x 797 ) / 1594
= 2 / 797
= 2
So, Greatest Common Divisor of 978, 804, 790, 797 is 1
