Given numbers are 861, 779, 220, 904
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 779) = 16359
GCD(861, 779) = ( 861 x 779 ) / 16359
= 861 / 779
= 861
Step2:
LCM(41, 220) = 9020
GCD(41, 220) = ( 41 x 220 ) / 9020
= 41 / 220
= 41
Step3:
LCM(1, 904) = 904
GCD(1, 904) = ( 1 x 904 ) / 904
= 1 / 904
= 1
So, Greatest Common Divisor of 861, 779, 220, 904 is 1
