GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 969) = 669579
GCD(691, 969) = ( 691 x 969 ) / 669579
= 691 / 969
= 691
Step2:
LCM(1, 223) = 223
GCD(1, 223) = ( 1 x 223 ) / 223
= 1 / 223
= 1
Step3:
LCM(1, 958) = 958
GCD(1, 958) = ( 1 x 958 ) / 958
= 1 / 958
= 1
So, Greatest Common Divisor of 691, 969, 223, 958 is 1
