Given numbers are 691, 813, 681, 222
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 813) = 561783
GCD(691, 813) = ( 691 x 813 ) / 561783
= 691 / 813
= 691
Step2:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
Step3:
LCM(1, 222) = 222
GCD(1, 222) = ( 1 x 222 ) / 222
= 1 / 222
= 1
So, Greatest Common Divisor of 691, 813, 681, 222 is 1
