GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 395) = 255565
GCD(647, 395) = ( 647 x 395 ) / 255565
= 647 / 395
= 647
Step2:
LCM(1, 562) = 562
GCD(1, 562) = ( 1 x 562 ) / 562
= 1 / 562
= 1
Step3:
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
= 1 / 449
= 1
So, Greatest Common Divisor of 647, 395, 562, 449 is 1
