Given numbers are 885, 475, 861, 691
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(885, 475) = 84075
GCD(885, 475) = ( 885 x 475 ) / 84075
= 885 / 475
= 885
Step2:
LCM(5, 861) = 4305
GCD(5, 861) = ( 5 x 861 ) / 4305
= 5 / 861
= 5
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 885, 475, 861, 691 is 1
