Given numbers are 205, 210, 653, 903
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(205, 210) = 8610
GCD(205, 210) = ( 205 x 210 ) / 8610
= 205 / 210
= 205
Step2:
LCM(5, 653) = 3265
GCD(5, 653) = ( 5 x 653 ) / 3265
= 5 / 653
= 5
Step3:
LCM(1, 903) = 903
GCD(1, 903) = ( 1 x 903 ) / 903
= 1 / 903
= 1
So, Greatest Common Divisor of 205, 210, 653, 903 is 1
