GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(863, 991) = 855233
GCD(863, 991) = ( 863 x 991 ) / 855233
= 863 / 991
= 863
Step2:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
Step3:
LCM(1, 889) = 889
GCD(1, 889) = ( 1 x 889 ) / 889
= 1 / 889
= 1
So, Greatest Common Divisor of 863, 991, 280, 889 is 1
