Given numbers are 777, 878, 783, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(777, 878) = 682206
GCD(777, 878) = ( 777 x 878 ) / 682206
= 777 / 878
= 777
Step2:
LCM(1, 783) = 783
GCD(1, 783) = ( 1 x 783 ) / 783
= 1 / 783
= 1
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 777, 878, 783, 809 is 1
