Given numbers are 649, 555, 431, 903
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 555) = 360195
GCD(649, 555) = ( 649 x 555 ) / 360195
= 649 / 555
= 649
Step2:
LCM(1, 431) = 431
GCD(1, 431) = ( 1 x 431 ) / 431
= 1 / 431
= 1
Step3:
LCM(1, 903) = 903
GCD(1, 903) = ( 1 x 903 ) / 903
= 1 / 903
= 1
So, Greatest Common Divisor of 649, 555, 431, 903 is 1
