Given numbers are 391, 281, 884, 903
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 281) = 109871
GCD(391, 281) = ( 391 x 281 ) / 109871
= 391 / 281
= 391
Step2:
LCM(1, 884) = 884
GCD(1, 884) = ( 1 x 884 ) / 884
= 1 / 884
= 1
Step3:
LCM(1, 903) = 903
GCD(1, 903) = ( 1 x 903 ) / 903
= 1 / 903
= 1
So, Greatest Common Divisor of 391, 281, 884, 903 is 1
