GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 697) = 452353
GCD(649, 697) = ( 649 x 697 ) / 452353
= 649 / 697
= 649
Step2:
LCM(1, 798) = 798
GCD(1, 798) = ( 1 x 798 ) / 798
= 1 / 798
= 1
Step3:
LCM(1, 242) = 242
GCD(1, 242) = ( 1 x 242 ) / 242
= 1 / 242
= 1
So, Greatest Common Divisor of 649, 697, 798, 242 is 1
