GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 943) = 19803
GCD(861, 943) = ( 861 x 943 ) / 19803
= 861 / 943
= 861
Step2:
LCM(41, 219) = 8979
GCD(41, 219) = ( 41 x 219 ) / 8979
= 41 / 219
= 41
Step3:
LCM(1, 798) = 798
GCD(1, 798) = ( 1 x 798 ) / 798
= 1 / 798
= 1
So, Greatest Common Divisor of 861, 943, 219, 798 is 1
