GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(225, 689) = 155025
GCD(225, 689) = ( 225 x 689 ) / 155025
= 225 / 689
= 225
Step2:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
Step3:
LCM(1, 838) = 838
GCD(1, 838) = ( 1 x 838 ) / 838
= 1 / 838
= 1
So, Greatest Common Divisor of 225, 689, 813, 838 is 1
