Given numbers are 691, 665, 798, 537
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 665) = 459515
GCD(691, 665) = ( 691 x 665 ) / 459515
= 691 / 665
= 691
Step2:
LCM(1, 798) = 798
GCD(1, 798) = ( 1 x 798 ) / 798
= 1 / 798
= 1
Step3:
LCM(1, 537) = 537
GCD(1, 537) = ( 1 x 537 ) / 537
= 1 / 537
= 1
So, Greatest Common Divisor of 691, 665, 798, 537 is 1
