The list of prime factors of all numbers are
Prime factors of 834 are 2 x 3 x 139
Prime factors of 855 are 3 x 3 x 5 x 19
Prime factors of 793 are 13 x 61
Prime factors of 390 are 2 x 3 x 5 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 834, 855, 793, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(834, 855) = 237690
GCD(834, 855) = ( 834 x 855 ) / 237690
= 834 / 855
= 834
Step2:
LCM(3, 793) = 2379
GCD(3, 793) = ( 3 x 793 ) / 2379
= 3 / 793
= 3
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 834, 855, 793, 390 is 1
