Given numbers are 645, 782, 789, 404
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 782) = 504390
GCD(645, 782) = ( 645 x 782 ) / 504390
= 645 / 782
= 645
Step2:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
Step3:
LCM(1, 404) = 404
GCD(1, 404) = ( 1 x 404 ) / 404
= 1 / 404
= 1
So, Greatest Common Divisor of 645, 782, 789, 404 is 1
