Given numbers are 420, 866, 523, 903
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 866) = 181860
GCD(420, 866) = ( 420 x 866 ) / 181860
= 420 / 866
= 420
Step2:
LCM(2, 523) = 1046
GCD(2, 523) = ( 2 x 523 ) / 1046
= 2 / 523
= 2
Step3:
LCM(1, 903) = 903
GCD(1, 903) = ( 1 x 903 ) / 903
= 1 / 903
= 1
So, Greatest Common Divisor of 420, 866, 523, 903 is 1
