GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 809) = 224902
GCD(278, 809) = ( 278 x 809 ) / 224902
= 278 / 809
= 278
Step2:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
Step3:
LCM(1, 793) = 793
GCD(1, 793) = ( 1 x 793 ) / 793
= 1 / 793
= 1
So, Greatest Common Divisor of 278, 809, 261, 793 is 1
