Given numbers are 123, 428, 556, 500
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 428) = 52644
GCD(123, 428) = ( 123 x 428 ) / 52644
= 123 / 428
= 123
Step2:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
Step3:
LCM(1, 500) = 500
GCD(1, 500) = ( 1 x 500 ) / 500
= 1 / 500
= 1
So, Greatest Common Divisor of 123, 428, 556, 500 is 1
