GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 782) = 253368
GCD(648, 782) = ( 648 x 782 ) / 253368
= 648 / 782
= 648
Step2:
LCM(2, 208) = 208
GCD(2, 208) = ( 2 x 208 ) / 208
= 2 / 208
= 2
Step3:
LCM(2, 259) = 518
GCD(2, 259) = ( 2 x 259 ) / 518
= 2 / 259
= 2
So, Greatest Common Divisor of 648, 782, 208, 259 is 1
