Given numbers are 789, 221, 895, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 221) = 174369
GCD(789, 221) = ( 789 x 221 ) / 174369
= 789 / 221
= 789
Step2:
LCM(1, 895) = 895
GCD(1, 895) = ( 1 x 895 ) / 895
= 1 / 895
= 1
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 789, 221, 895, 809 is 1
