Given numbers are 691, 569, 847, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 569) = 393179
GCD(691, 569) = ( 691 x 569 ) / 393179
= 691 / 569
= 691
Step2:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 691, 569, 847, 865 is 1
