Given numbers are 878, 102, 809, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(878, 102) = 44778
GCD(878, 102) = ( 878 x 102 ) / 44778
= 878 / 102
= 878
Step2:
LCM(2, 809) = 1618
GCD(2, 809) = ( 2 x 809 ) / 1618
= 2 / 809
= 2
Step3:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
So, Greatest Common Divisor of 878, 102, 809, 731 is 1
