The list of prime factors of all numbers are
Prime factors of 835 are 5 x 167
Prime factors of 102 are 2 x 3 x 17
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 170 are 2 x 5 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 835, 102, 840, 170
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(835, 102) = 85170
GCD(835, 102) = ( 835 x 102 ) / 85170
= 835 / 102
= 835
Step2:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
Step3:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
So, Greatest Common Divisor of 835, 102, 840, 170 is 1
