GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(868, 819) = 101556
GCD(868, 819) = ( 868 x 819 ) / 101556
= 868 / 819
= 868
Step2:
LCM(7, 647) = 4529
GCD(7, 647) = ( 7 x 647 ) / 4529
= 7 / 647
= 7
Step3:
LCM(1, 444) = 444
GCD(1, 444) = ( 1 x 444 ) / 444
= 1 / 444
= 1
So, Greatest Common Divisor of 868, 819, 647, 444 is 1
