GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(569, 646) = 367574
GCD(569, 646) = ( 569 x 646 ) / 367574
= 569 / 646
= 569
Step2:
LCM(1, 727) = 727
GCD(1, 727) = ( 1 x 727 ) / 727
= 1 / 727
= 1
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 569, 646, 727, 691 is 1
