Given numbers are 318, 390, 691, 903
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(318, 390) = 20670
GCD(318, 390) = ( 318 x 390 ) / 20670
= 318 / 390
= 318
Step2:
LCM(6, 691) = 4146
GCD(6, 691) = ( 6 x 691 ) / 4146
= 6 / 691
= 6
Step3:
LCM(1, 903) = 903
GCD(1, 903) = ( 1 x 903 ) / 903
= 1 / 903
= 1
So, Greatest Common Divisor of 318, 390, 691, 903 is 1
