GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(788, 884) = 174148
GCD(788, 884) = ( 788 x 884 ) / 174148
= 788 / 884
= 788
Step2:
LCM(4, 731) = 2924
GCD(4, 731) = ( 4 x 731 ) / 2924
= 4 / 731
= 4
Step3:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
So, Greatest Common Divisor of 788, 884, 731, 647 is 1
