Given numbers are 905, 728, 636, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 728) = 658840
GCD(905, 728) = ( 905 x 728 ) / 658840
= 905 / 728
= 905
Step2:
LCM(1, 636) = 636
GCD(1, 636) = ( 1 x 636 ) / 636
= 1 / 636
= 1
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 905, 728, 636, 789 is 1
