GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(343, 207) = 71001
GCD(343, 207) = ( 343 x 207 ) / 71001
= 343 / 207
= 343
Step2:
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
= 1 / 878
= 1
Step3:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
So, Greatest Common Divisor of 343, 207, 878, 647 is 1
