Given numbers are 905, 280, 556, 682
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 280) = 50680
GCD(905, 280) = ( 905 x 280 ) / 50680
= 905 / 280
= 905
Step2:
LCM(5, 556) = 2780
GCD(5, 556) = ( 5 x 556 ) / 2780
= 5 / 556
= 5
Step3:
LCM(1, 682) = 682
GCD(1, 682) = ( 1 x 682 ) / 682
= 1 / 682
= 1
So, Greatest Common Divisor of 905, 280, 556, 682 is 1
