Given numbers are 691, 809, 504, 890
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 809) = 559019
GCD(691, 809) = ( 691 x 809 ) / 559019
= 691 / 809
= 691
Step2:
LCM(1, 504) = 504
GCD(1, 504) = ( 1 x 504 ) / 504
= 1 / 504
= 1
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 691, 809, 504, 890 is 1
