Given numbers are 904, 690, 903, 439
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(904, 690) = 311880
GCD(904, 690) = ( 904 x 690 ) / 311880
= 904 / 690
= 904
Step2:
LCM(2, 903) = 1806
GCD(2, 903) = ( 2 x 903 ) / 1806
= 2 / 903
= 2
Step3:
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
= 1 / 439
= 1
So, Greatest Common Divisor of 904, 690, 903, 439 is 1
