GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(788, 842) = 331748
GCD(788, 842) = ( 788 x 842 ) / 331748
= 788 / 842
= 788
Step2:
LCM(2, 495) = 990
GCD(2, 495) = ( 2 x 495 ) / 990
= 2 / 495
= 2
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 788, 842, 495, 790 is 1
