Given numbers are 191, 697, 221, 777
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(191, 697) = 133127
GCD(191, 697) = ( 191 x 697 ) / 133127
= 191 / 697
= 191
Step2:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
Step3:
LCM(1, 777) = 777
GCD(1, 777) = ( 1 x 777 ) / 777
= 1 / 777
= 1
So, Greatest Common Divisor of 191, 697, 221, 777 is 1
