The list of prime factors of all numbers are
Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5
Prime factors of 872 are 2 x 2 x 2 x 109
Prime factors of 905 are 5 x 181
Prime factors of 357 are 3 x 7 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 810, 872, 905, 357
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 872) = 353160
GCD(810, 872) = ( 810 x 872 ) / 353160
= 810 / 872
= 810
Step2:
LCM(2, 905) = 1810
GCD(2, 905) = ( 2 x 905 ) / 1810
= 2 / 905
= 2
Step3:
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
= 1 / 357
= 1
So, Greatest Common Divisor of 810, 872, 905, 357 is 1
